I just received a Diablo Sport InTune3 programmer for a 2017 GM and I want to know if the dealer can detect use if I revert to factory tune prior to taking to dealer..
Diablo says NO, they cannot.. What Say You???
I really hope not as I really need to tune the transmission for better shifting..
Thanks For Your Help,
Thirdcoast
