Up to 30% more power for your Vauxhall

Vauxhall chip tuning: questions
Does the GAN module affect my Vauxhall warranty?
No. The module does not change the ECU software and can be removed at any time, so your manufacturer’s warranty is preserved. We also give an engine warranty: 2 years with the GAN GT, 1 year with the GAN GTL.
Tuning box or ECU remap: which should I choose?
An ECU remap permanently changes the maps in the ECU and leaves a trace in the flash counter. The GAN tuning module adjusts the sensor signals instead: the ECU stays in factory condition, and you can return the car to stock in about a minute.
