so what kind of numbers did everyone gain? i have been thinking of getting a tune since i have a lot of mods you can say. anyone think i should get a tune with mrev2, spacer, ztube, k&n filter, hfcs, and true catback?

 

^Yea

What else can you add besides headers, thats pretty much it for bolt ons.

 

which i don't want..

 

Sorry to bump this. But nobody has yet to answer a previous question about the price for the Osiris tune. What would I be looking at to tune/dyno a AT G coupe w/ M2 cat-back, resonated test pipes, Iso thermal spacer, short ram intake with heat shield, grounded cables? I don't plan on adding any more performance mods.
