Hypertech Max Energy Power Programmers

Hypertech's Max Energy power programmers extract every bit of energy possible from every molecule of fuel, increasing miles-per-gallon at part throttle and horsepower at wide-open throttle. Max Energy programmers are even Internet updateable with the included USB cable. Additional features (depending on the vehicle application) include: * Raise the top-speed limiter to match the speed rating of high performance tires * Raise the engine's rpm limiter for increased performance * Adjust individual automatic transmission shift points and shift firmness * Recalibrate speedometer and odometer for non-stock tire sizes and/or gear ratio changes * Lower the cooling fan on/off temperatures to match the thermostat rating * Read and clear diagnostic trouble codes and turn off "check engine" lights * Ability to adjust settings or go back to stock calibration at any time Show Less
