Hahaha, I’d be careful. We tried to warranty an 09 6.6 and GM sent someone out to inspect the truck, Decided that there had been a tune done on it - Then removed and voided the guys warranty, leaving him with a 28,000 repair bill.

GM is hardcore against using aftermarket tuning on the duramax’s, be careful when getting carried away with your tuning - GM has gotten alot more strict with warranty claims since we became “government motors”

beat me to it.

GM is very strict with there warranty’s now. just a heads up
