So your dealer did the install for you… what, if anything, did they say about your warranty? Do you still have some of the factory warranty left?
I have a CPO warranty and have held off on a tune b/c of my concern that my warranty / CPO will be voided (at least as to the engine)…. If the dealer is an authorized installer, maybe they "look the other way" if you have a motor issue?
Does the car pop/crackle more or just faster?
