The question that I have is, if I get a exhaust system after I get the tuner, will it effect the tune that I already got? Will I have to get it retuned or will it be ok?

*Edit* I am getting the SCT XCalibrator 2 Tuner

 

It might effect it slightly but nothing major. Depends on what exhaust system we talkin about here? Headers and everything, just cat-backs, what?

 

Might effect like 2 horses if that. If its just the Aft Cats or Cat Backs..... Not really a difference if you retune or not. If its the whole system, headers on back, then go ahead just to ease your mind that your squeezing about 1 to 2 horses for your power pleasure!

 

You dont need a retune. and if you do get one you woulnt notice a difference.

 

Thanks.
