Increase GMC Performance & Gain MPG
Our GMC Performance Chips combine the feel of a more powerful engine, with the economy of a small motor. You can easily install the GMC ECU Chip by plugging it directly into your OBD/Diagnostic Port. The performance chip loads new, pre-tuned and motor-specific fuel maps onto your ECU, improving throttle response and overall performance for your GMC.
Does your GMC have after-market modifications? Not a problem with this ECU Tuning solution. Rocket Chip Performance Chips will adapt to your modifications and provide the tuning necessary for your specific vehicle. All tunes are dyno and road tested to ensure optimal results.
60-Second Performance Chip Installation: No Wire Cutting. No Tools are Needed.
30-Day Money-Back Guarantee
GMC Performance Chips are an industry leader in improving performance and MPG.
GMC Performance Chips are best-in-class horsepower, torque, and fuel economy gains. A 60-second plug-n-play install is all it takes to increase the performance and mileage of your vehicle. Performance is improved by dyno tuning your GMC, creating a more efficient fuel map changing air/fuel mixtures. The tuning improves the timing and boosts pressure (if your engine applies), all while maintaining the vehicle warranty. The performance chip is easily unplugged for emission testing and diagnostic work.
No modifications are required for your performance chip to work on your vehicle. If you modify your vehicle in the future, the performance chip will recognize the modifications, and adapt and correct the air/fuel mixtures. If you ever wish to return your vehicle to stock form, simply unplug the performance chip from the OBD2 port, and the factory ECU will resume with the original fuel map. Keep an eye out for vehicle performance products offering impossible numbers with just a resistor. Rocket Chip Performance Chips are genuine Performance Chips.
