That being said; although you were told by the seller that you still have some powertrain warranty remaining, if you have engine issues and it is discovered by GM that you have had a tune... they most likely will not honor any remaining warranty.
If it were my car (very nice, by the way) I would go with CAI intake, quality headers, a nice sounding exhaust system, and a custom dyno tune (to include AFM disable and more aggressive shift points).

Thank you! And yeah unfortunately the warranty will keep me from doing a few things. But bolt ons are a go all day.. Cai, headers, exhaust are definetly on the list. Gotta find a good place to dyno tune
