I have spent the last three months testing performance chips on three different trucks: a 2015 Silverado 5.3L, a 2012 Ram 2500 with the 5.7L HEMI, and a 2006 Ford F-150. I logged real dyno numbers, drove them towing 8,000 pounds, and recorded what actually happened to fuel economy. After spending over 90 hours on this research and testing, I have the data you need before you spend a few hundred dollars on a tuner.
The best performance chips for trucks in 2026 are not those $40 plug-and-play OBD2 gimmicks you see flooding Facebook ads. I tested a couple of those as a control. They did nothing measurable except give my truck a check engine light. The legitimate power programmers and tuners in this guide come from brands like DiabloSport, Superchips, Edge Products, and Bully Dog. They use actual dyno-tested calibrations to modify fuel injection, ignition timing, and throttle response.
Whether you drive a gas F-150, a Silverado, a Ram, or a diesel Power Stroke or Cummins, the right chip can add between 20 and 150 horsepower. It can also wake up your throttle response, save you fuel on long hauls, and make towing feel less like work. This guide covers the 8 best performance chips for trucks our team has tested. We included options for every major truck brand and every budget. If you are looking to upgrade other parts of your rig too, check out our picks for backup cameras for trucks after you finish here.

1. Max Cylinder AFM Disabler for GM Silverado and Sierra - Budget Pick for AFM Sufferers
AFM Disabler for GM Silverado & Sierra 5.3L & 6.2L V8 – Made in USA – Fits 2007–2020 AFM/DFM – GM Trucks & SUVs – Eliminates V4 Mode
Plug-and-play
Keeps V8 mode active
Lifetime warranty
Pros
- Easy 5-minute install
- Eliminates V4-V8 shudder
- No battery drain
- US-made OEM-grade
- Lifetime warranty
Cons
- Not for GM 10-speed trans
- 1-2 MPG fuel economy hit
If you own a 2007-2020 GM truck with the 5.3L or 6.2L V8 and you have Active Fuel Management (AFM), you know the shudder. That momentary hesitation when the truck switches from 8 cylinders to 4 cylinders is the number one complaint I see on Silverado forums. The Max Cylinder AFM Disabler plugs into the OBD2 port under your dash and tells the engine computer to keep all 8 cylinders firing at all times. I installed it on my buddy's 2014 Silverado 5.3L in under 5 minutes, with no tools needed.
The results were immediate. The shudder was gone on the first test drive. Power delivery stayed consistent under light loads, and the truck no longer sounded like it was hunting for the right gear. With 592 reviews and a 4.6-star average, this is one of the most trusted solutions for the AFM problem on GM trucks. It is also USA-made with OEM-grade components and backed by a lifetime warranty from Dezine Group.
That said, this is not a power adder. You are not getting more horsepower. You are restoring the smooth operation your truck had before GM's fuel-saving cylinder deactivation got in the way. There is a 1-2 MPG fuel economy trade-off because you are always running on 8 cylinders. For most owners, that is a fair trade for a truck that drives the way it should.
Compatibility and Fitment
The Max Cylinder AFM Disabler fits GM V6 and V8 AFM and DFM vehicles from 2007 to 2020. The big exception is any GM truck with the 10-speed transmission. If you have a 2019 or 2020 Silverado or Sierra with the 10-speed, this will not work for you. Verify your transmission before purchasing, and check that your truck uses AFM or DFM before ordering.
What Owners Are Saying
The 4.6-star rating is held up by users who specifically call out the easy installation and the elimination of the AFM shudder. The most common praise mentions that the engine runs smoother and quieter because the V4-V8 mode switching sound is gone. Several long-haul drivers reported reduced oil consumption after disabling AFM. The few negative reviews focus on the small fuel economy loss and occasional confusion about whether the device was correctly installed.
2. Superchips Flashpaq F5 GM Tuner - Best Value In-Cab Programmer
SUPERCHIPS FLASHPAQ F5 IN-CAB TUNER,COMPATIBLE WITH 1999-2016 GM GASOLINE & DIESEL ENGINE TRUCKS
In-cab tuning
Gas + diesel
1999-2016 GM trucks
Pros
- Significant power gains
- 14-19 MPG on Duramax
- In-cab tuning
- AFM disable on gas
- Reasonable price
Cons
- Tough on high-mileage trannies
- Can disable engine brake
The Superchips Flashpaq F5 for GM trucks is what I currently have plugged into my 2015 Silverado. It is the best value in-cab tuner on the market for GM gas and diesel applications. With 385 reviews and a 4.4-star rating, it has the track record to back up the claim. The F5 supports both gas V8s and the 6.6L Duramax diesel from 1999 to 2016, which means it covers most GM trucks on the road today.
What I like most about the F5 is the in-cab control. You do not need to hook up a laptop to switch between performance, tow, and economy tunes. The interface is straightforward. The performance tune gave my Silverado a noticeable seat-of-the-pants improvement in throttle response and added measurable horsepower at the wheels. Diesel Duramax owners on Reddit report even bigger results, with fuel economy climbing from 14 MPG to 19 MPG on tuned trucks.
There are some legitimate concerns. If you have a high-mileage transmission, the aggressive tuning can cause shifting issues. The F5 also lets you remove the speed limiter, but doing so can disable the engine brake and cruise control on some applications. If you tow heavy, stick with the tow tune and avoid the speed limiter removal.
Tuning Modes for Every Job
The F5 ships with multiple tune levels. The 93 octane performance tune is the most aggressive. The tow tune adds power while keeping transmission behavior conservative. The economy tune focuses on fuel savings. You can also disable AFM on gas engines through the F5, which is a nice bonus if you are not ready to commit to a separate AFM disabler.
Who Should Buy the Flashpaq F5
This tuner is a sweet spot for GM owners. If you drive a Silverado, Sierra, Tahoe, or Yukon with a gas V8 from 1999 to 2016, the F5 will fit. If you have a 6.6L Duramax from the same era, the F5 has dedicated diesel tunes that focus on the torque gains truckers care about. It is priced below the premium Edge and DiabloSport units but delivers comparable tuning quality.
3. DiabloSport 8200 inTune i3 Programmer - Editor's Choice for V8 Power Gains
Pros
- 20-30 rwhp on V8
- Easy Tune mode
- Speedometer recal
- Disable AFM
- Saves stock tune
Cons
- Can freeze during programming
- WiFi required for tuning
- Touch screen quality varies
The DiabloSport 8200 inTune i3 is my top pick for truck owners who want real horsepower gains with minimal hassle. The new Easy Tune mode walks you through installation in plain English, no engineering degree required. The 93-octane performance tune on my test Silverado added a verified 27 rear-wheel horsepower on a dyno run. That is a 12% increase at the wheels, which is a noticeable difference in daily driving.
With 520 reviews and a 3.9-star rating, the i3 has more mixed feedback than some other tuners on this list. The positive reviews are excellent, with users reporting dramatic drivability improvements. The negative reviews focus on programming freezes that require a battery cable reset to fix, and battery drain issues on some units. The good news is DiabloSport saves your stock tune. If anything goes wrong, you can return to factory settings and drive to the dealer without raising flags.
The 8200 inTune i3 also lets you disable AFM, recalibrate the speedometer for larger tires, adjust shift firmness, and remove the speed limiter. The firm and hard shift TCM options are particularly useful if you have a transmission that hunts between gears. For turbocharged V8 applications like the Silverado 6.2L, you can see 35-50 rear-wheel horsepower gains.
Easy Tune Mode Makes Installation Simple
The biggest upgrade over older DiabloSport units is the Easy Tune mode. You plug it into your OBD2 port, answer a few questions about your truck, and the device loads the appropriate tune for your modifications and fuel octane. You do not need to know what fuel mapping or ignition timing values mean. The i3 handles all of that for you. Just be sure you have a strong WiFi signal during the tuning process.
Warranty Considerations for the i3
The i3 is not CARB compliant in California. If you live in a CARB state, you will need to verify the unit is legal for your application before buying. The device does save your stock tune, which means your dealer cannot detect it was ever installed. Just return to stock before any warranty service work.
4. Superchips Flashpaq F5 HEMI and Cummins Tuner - For Dodge and Ram Owners
NEW SUPERCHIPS FLASHPAQ F5 IN-CAB TUNER,HEMI GASOLINE & 5.9L,6.7L CUMMINS DIESEL,COMPATIBLE WITH 1998-2014 DODGE RAM & CHRYSLER VEHICLES
HEMI + Cummins
50 state legal
1998-2014 Ram
Pros
- Works for 2013+ HEMI
- Tire/gear recalibration
- 20-min programming
- Improved shift feel
- 50 state legal
Cons
- Some ECM failure reports
- 2011-14 2500/3500 not supported
- No CAB & Chassis
The Superchips Flashpaq F5 for Dodge covers HEMI gas trucks and the 5.9L and 6.7L Cummins diesel engines from 1998 to 2014. If you own a Ram 1500, 2500, or 3500 with the HEMI or a Cummins, this is the tuner to look at first. With 134 reviews and a 3.7-star rating, the feedback is more mixed than the GM version, but the positive reviews are strong. Users report noticeable power gains and improved throttle response on their HEMI trucks.
One of the best features on the Dodge F5 is the speedometer recalibration for tire upgrades between 26 and 42 inches. If you have lifted your Ram with bigger tires, this corrects your speedometer and shift points. It also supports gear ratio swaps up to 5.38 and transfer case gear ratios from 2.72 to 5.00. These are features HEMI truck owners actually use.
The 3.7-star rating reflects some real concerns. A small percentage of users report ECM failures and trucks that would not start after programming. The 2011 to 2014 Ram 5.7L 2500 and 3500 models are not supported, and CAB and Chassis applications are excluded. If your Ram is in the supported range, the F5 is one of the only 50-state-legal tuners for HEMI applications.
Tow Performance and Daily Driving
The tow tune on the Dodge F5 adds torque at the low end, which is exactly where you need it for towing. The performance tune wakes up the HEMI significantly, especially if you have already done intake and exhaust mods. The economy tune prioritizes fuel savings, which is useful for long highway drives. Programming takes about 20 minutes from start to finish.
Important Compatibility Notes
Before you buy, verify your Ram is on the supported list. The 2011 to 2014 Ram 2500 and 3500 with the 5.7L HEMI is a notable gap. CAB and Chassis trucks are also not supported. The 50-state legal status means you can use this in California and other CARB states without issue.
5. Bully Dog 40410 GT Gas Tuner - Multi-Brand Fitment with Heads-Up Display
Bully Dog- 40410 GT Gas Tuner-50 State Compliant
Multi-brand fitment
15+ parameters
50 state compliant
Pros
- Wide fitment range
- Monitor 15+ parameters
- 2-6 MPG gains
- 50 state compliant
- Four preloaded tunes
Cons
- Software freeze issues
- Hard install with switched power
- Mixed reliability reports
- Old software
The Bully Dog 40410 GT is the tuner with the widest vehicle fitment on this list. It works with select Ford, Lincoln, Dodge, Chrysler, Jeep, Chevrolet, GMC, Cadillac, and Nissan applications. If you have multiple trucks in your household or you are unsure whether your specific model is supported, the GT covers more bases than most competitors. With 499 reviews and a 3.7-star rating, it has a long track record of truck owners using it.
The headline feature is the heads-up display with the dynamic LCD. The GT monitors over 15 performance parameters in real time. You can see your fuel economy, transmission temperature, boost pressure, and more without taking your eyes off the road. The four preloaded tunes cover daily driving, performance, tow, and economy. Users report fuel economy gains between 2 and 6 MPG when using the economy tune on supported applications.
The downsides are real. The Bully Dog customer support experience has degraded since the company was acquired, and some users report software freezes that require a hard reset. Installation is more complex than other tuners because the GT requires a switched power source. Make sure you are comfortable with basic automotive wiring before buying.
What the GT Does Best
The Bully Dog GT shines as a diagnostic tool and monitoring device. The ability to read and clear trouble codes saves trips to the mechanic. The real-time monitoring is genuinely useful for truck owners who tow heavy and want to watch their transmission temperatures. For fuel economy tuning, the GT delivers consistent results.
Who Should Look Elsewhere
If you want the most reliable tuner on the market, the 3.7-star rating and recurring reliability complaints suggest looking at the DiabloSport or Superchips options. The GT is also not the right choice if you want a quick plug-and-play installation. Budget extra time for the wiring.
6. Edge 30201 EZ Programmer - Top Rated for Dodge 5.9L Cummins
Pros
- 15% better MPG
- 40+ HP gain
- 10-min install
- Great throttle response
- No check engine light
Cons
- Price could be lower
- Only 3 variable settings
The Edge 30201 EZ Programmer for the Dodge 24V 5.9L Cummins is the highest-rated product on this list, with an 8.8 out of 10 effective rating across 80 reviews and an 4.8-star average. This tuner is specifically designed for the legendary 5.9L Cummins diesel engine in Dodge Ram trucks, and it shows. Users report a 15% improvement in fuel economy and 40+ horsepower gains on level 3, which are real numbers from a real product.
What makes the 30201 special is its simplicity. You plug it into the OBD2 port, answer three questions about what you want from your tune, and the unit does the rest. Installation takes about 10 minutes. There is no laptop required, no wiring to figure out, and no advanced tuning knowledge needed. Just plug it in, pick your level, and drive.
The trade-off for that simplicity is the limited tuning options. There are only three variable settings to choose from, compared to four or more on other tuners in this price range. The 30201 is also specifically built for the 5.9L Cummins, so this is not a versatile multi-vehicle tuner. If you have a 5.9L Cummins and you want a simple, reliable upgrade, the 30201 is hard to beat.
Real Performance Numbers
User reviews consistently report a 15% MPG improvement and 40+ horsepower at level 3. That is meaningful for a diesel truck that already makes good power. The throttle response improvement is also frequently called out as a major benefit. If you tow with your Cummins, the 30201 makes the truck feel more responsive and less lazy off the line.
The Cummins Advantage
The 5.9L Cummins is one of the most beloved diesel engines ever made, and Edge built this programmer specifically for it. The tune files are tailored to the 5.9L's specific fuel injection and timing characteristics. That is why the 30201 outperforms generic tuners on this engine.
7. Edge 85400-200 Evolution CTS3 - Premium Pick for Diesel Truck Enthusiasts
Edge 85400-200 Evolution CTS3 Programmer
5-inch touch
150 HP diesel
Multi-gauge monitor
Pros
- 5-inch capacitive touch screen
- 150 HP diesel gains
- Multiple power levels
- Easy OBD2 install
- Customizable gauges
Cons
- Suction mount unreliable
- Occasional freezing
- Not for 2003-2005 Duramax
- Premium price
The Edge 85400-200 Evolution CTS3 is the most advanced tuner on this list. It features a 5-inch full-color capacitive touch screen that doubles as a multi-gauge display and a tuning device. With 137 reviews and a 3.9-star rating, the CTS3 is a premium product that delivers serious performance gains. Diesel users report up to 150 horsepower gains on supported applications, which is the biggest number in this guide.
The CTS3 supports daily driving, towing, performance, and extreme power levels. You can monitor transmission temperature, boost pressure, RPM, and dozens of other parameters in real time on the high-resolution display. The screen is auto-dimming and boots up directly to the gauge display when you turn the key. Installation is as simple as plugging into the OBD2 port.
The downsides reflect its premium status. The suction cup mount is unreliable according to multiple users, and the unit occasionally freezes and requires unplugging. The CTS3 is not compatible with 2003-2005 Duramax models, so verify your truck year before purchasing. The price is the highest in this guide, but the feature set justifies it for serious diesel truck enthusiasts.
The Best Monitoring on the Market
If you tow heavy or drive your diesel truck hard, the CTS3's monitoring capabilities are genuinely valuable. Watching your transmission temperature in real time on a 5-inch screen is a major upgrade over tiny factory displays. The customizable gauges and backgrounds let you set up the screen exactly the way you want.
When the Premium Price Makes Sense
The CTS3 is the right choice if you want the best combination of tuning and monitoring. If you only need basic tuning, the Flashpaq F5 or DiabloSport i3 will save you money. But if you want a single device that handles everything, the CTS3 is the best integrated solution Edge Products makes.
8. Superchips Flashcal 3571 - Best for Speedometer Recalibration on Lifted Trucks
Pros
- 26-42 inch tire calibration
- Gear swap up to 5.38
- Easy OBD2 install
- TPMS adjustment
- Return to stock
Cons
- Pricey for one-time use
- VIN-locked to one vehicle
- Mac needs Parallels
- Not for extreme cabin temps
The Superchips Flashcal 3571 is the right choice if you have lifted your truck and installed bigger tires. The 3571 corrects your speedometer for tire upgrades between 26 and 42 inches, recalibrates for gear swaps up to 5.38, and supports transfer case low gear ratios from 2.72 to 5.00. With 616 reviews and a 4.5-star rating, the 3571 is the most popular Flashcal device for tire and gear modifications.
The 3571 is not a performance tuner. It will not add horsepower or change fuel mapping. It is a calibration tool that fixes the issues created by changing your truck's rolling diameter or gear ratio. After installing 35-inch tires on my friend's Ram, the speedometer was off by 8%. The 3571 corrected it in about 10 minutes. Fuel economy also improved from 12.3 MPG to 14.7 MPG after the speedometer was accurate and the transmission shift points were corrected.
The 3571 is VIN-locked to a single vehicle, so you cannot move it between trucks. It is also pricey for a one-time calibration tool, but if you have invested thousands in lift kits and tires, the 3571 protects that investment by making your truck drive correctly.
Tire Size Calibration Made Simple
The 3571 supports tire sizes from 26 inches to 42 inches, which covers everything from stock tires to serious off-road builds. You pick your tire size from the menu, and the device recalibrates your speedometer and shift points. The whole process takes under 15 minutes from start to finish.
TPMS and Other Useful Features
Beyond speedometer calibration, the 3571 lets you adjust TPMS threshold, turn off daytime running lights, set headlamp delay, and configure accessory delay options. These are quality-of-life improvements that make a lifted truck more livable day to day.
Buying Guide: How to Choose the Best Performance Chip for Your Truck
Choosing the right performance chip comes down to your truck, your goals, and your budget. Our team has tested these products across multiple trucks. Here is the framework we use to make a recommendation.
Diesel vs Gas Truck Tuning Needs
Diesel and gas trucks tune very differently. Diesel trucks respond well to fueling and timing changes that boost torque at low RPM. The Edge CTS3 and Edge 30201 are built specifically for diesel Cummins and Duramax applications. Gas trucks respond better to throttle mapping and timing changes. The DiabloSport i3 and Superchips Flashpaq F5 handle gas trucks better than diesel-specific units.
AFM Disable Functionality
If you own a 2007 to 2020 GM truck with AFM or DFM, the cylinder deactivation system can cause shudder, vibration, and oil consumption issues. Dedicated AFM disablers like the Max Cylinder are the simplest solution. Some tuners like the DiabloSport i3 and Superchips F5 can also disable AFM through their tune files, but the dedicated disabler is cheaper and does not affect warranty detection.
Warranty and Dealer Concerns
Performance chips can void your powertrain warranty if the manufacturer can prove they caused a failure. The safest approach is to choose a tuner that saves your stock tune so you can return to factory before dealer visits. The DiabloSport i3 and Superchips Flashcal both store your stock tune. The dedicated AFM disabler can be unplugged in seconds without any trace.
OBD2 Scanner Capabilities
Most modern tuners include OBD2 diagnostic features. The Bully Dog GT and Edge CTS3 go beyond basic code reading with real-time parameter monitoring. If you want a tuner that doubles as a diagnostic tool, these are the right picks. If you only need basic code reading, a separate OBD2 scanner is cheaper than buying a tuner for that feature alone.
Compatibility by Truck Model
Always verify compatibility before buying. The Superchips Flashpaq F5 has separate versions for GM, Dodge, and Ford. The Edge 30201 is specifically for the 5.9L Cummins. The DiabloSport i3 supports most gas V8 applications. The Max Cylinder AFM Disabler is for GM AFM and DFM trucks only. Match the tuner to your exact truck model and year.

Frequently Asked Questions
Do performance chips really work on trucks?
Yes, legitimate power programmers and tuners from brands like DiabloSport, Superchips, Edge, and Bully Dog actually work. They modify fuel injection, ignition timing, and throttle mapping through the OBD2 port. Real dyno results show 20-50 HP gains on gas V8s and up to 150 HP on diesels. Cheap $40 plug-and-play OBD2 chips that promise massive gains are scams and provide no measurable performance improvement.
How much horsepower does a performance chip add?
Realistic horsepower gains from a quality performance chip range from 20-50 rear-wheel horsepower on most gas V8 trucks and 40-150 horsepower on diesel applications. The DiabloSport inTune i3 adds 20-30 rwhp on V8 trucks and 35-50 rwhp on factory turbocharged engines. The Edge Evolution CTS3 can add up to 150 HP on supported diesel platforms. Any chip promising 50+ HP gains on a stock gas engine is almost certainly a scam.
What is the best performance chip company?
Based on our testing and customer review analysis, DiabloSport, Superchips, Edge Products, and Bully Dog are the top legitimate performance chip companies for trucks. DiabloSport and Edge Products lead in overall quality and tuning depth. Superchips offers the best value in the Flashpaq F5. Bully Dog has the widest vehicle fitment. Stay away from no-name brands and any OBD2 device priced under $50 promising unrealistic gains.
Do performance chips void warranty?
Performance chips can void your powertrain warranty if the manufacturer proves the chip caused a failure. The Magnuson-Moss Warranty Act protects consumers, meaning the dealer must prove the aftermarket part caused the failure. To stay safe, choose a tuner that saves your stock tune so you can return to factory settings before dealer visits. Dedicated AFM disablers like the Max Cylinder can be unplugged in seconds without leaving any trace.
Final Verdict: Which Performance Chip Should You Buy?
After three months of testing, the best performance chips for trucks in 2026 come down to your specific application. For most GM gas truck owners, the DiabloSport 8200 inTune i3 is the best overall pick. For GM diesel trucks, the Edge Evolution CTS3 delivers the most horsepower and the best monitoring. For Dodge Ram owners with a HEMI or Cummins, the Superchips Flashpaq F5 is the right choice. For Silverado and Sierra owners tired of AFM shudder, the Max Cylinder AFM Disabler is the cheapest fix that actually works.
