Up to 30% more power for your GMC
Our GMC catalog covers 28 engines (models: 9, generations: 9). For 14% of the engines there are the GAN GT (up to 30% more power) and GAN GTL (up to 25%) tuning boxes; for 24 naturally aspirated engines, the GAN GA and GAN GA+ (up to 12%). Each engine’s figures are on its own page.
GMC plug-in remap: no changes to the ECU software
The tuning box sits between the sensors and the engine control unit (ECU) and adjusts their signals – unlike a flash remap, which rewrites the ECU. Your manufacturer’s warranty is preserved: the ECU software is never changed, and the box can be removed at any time.

GMC remapping: questions
Will a tuning box affect my GMC warranty?
No. The box does not change the ECU software and can be removed at any time, so your manufacturer’s warranty is preserved. On top of that, we give an engine warranty: 2 years with the GAN GT, 1 year with the GAN GTL.
Tuning box or remap: which should I choose?
A flash remap permanently rewrites the maps in the ECU and leaves a trace in the flash counter. The GAN tuning box adjusts the sensor signals instead: the ECU stays in factory condition, and you can return the car to stock in about a minute. A flash remap can be the better choice if the engine has upgraded hardware, or if the car is out of warranty and you accept the risks.
