May 13, 201016 yr #4 Definitely need a tune...Exhaust change Inc dump and cat will cause overboost!!!Don't put in tune either!!! That will just fark the engine even more!!! Will increase the boost and timing and will not be suited to exhaust (the generic tunes are for stock exhaust!!!)Custom tune is a must!!!
