Hey! Im about to be a new GTO owner and I cant wait! My plan is to first replace the shifter with a B and M or a 5.0 (recomendations?) After that, I want a CAI and a cat back system, probably Corsa, folowed by a performance tune. Should I do the tune last, after the instalation of the intake/exhaust? Also, if I were to get the perameters from someone who has similar mods who had a tune done on a dyno, could I give those perameters to a shop and have it tuned without a dyno?
Another thing. Would adding a cat back system and a CAI be useless without a tune? Thanks guys and gals
