I just wanted to know what kind of differences I would see if I tuned my srt-4 which has stage 2 with toys, mopar bov, k&n typhoon cold air intake, maxx fabb modified borla exaust and downpipe without cat, and I think thats everything I have that affects horsepwer. I just would like to know what kind of gains I would see and what exackly I would need to tune. Thanks in advance.
