After the chip tuning (ecu) software application we have prepared in order to make the 420 / 440 engine power produced by your GMC Sierra vehicle efficient in world norms, we foresee a performance increase of 420 / 440. After the + 20 / + 21 power increase gained, it is prepared by protecting your exhaust emission values in a way that will not disturb the environment (not emit smoke).

All our software is tested on a load type dyno for both power delivery and fuel efficiency. Our ability to extract maximum power while maintaining optimum reliability is the biggest factor that sets us apart.

The chip tuning (ecu) software process to be applied to the engine of your GMC Sierra vehicle takes an average of 1 hour. For more information, please see our Frequently Asked Questions section.
