Choose Hummer model from the list below to check how much power and torque of your car can increase. We offer only tested solutions based on measurement data from the dynamometer.
Improve your car's performance, engine power and torque thanks to our chiptuning files for Hummer. All files available in TC Performance are custom made by experienced engineers, programmers and tuners and tested on two Dyno Project dynamometers 4x4.
Hummer chip tuning can be done in two ways - through the OBD2 diagnostic connector or through the engine control unit (ECU). Increasing the power of Hummer is done by remapping car engine. There are no worries about compatibility or unstable engine operation.
Hummer is a car susceptible to ECU tuning. Our experience and knowledge about modifications and the results of our work are confirmed by the diagrams obtained on a professional chassis dynamometer 4x4.
Car testing results before and after increasing the power, show real benefits of chiptuning Hummer.
