Well, I been having problems with my SC...I have dump almost 3/4 of Premium fuel these past 2 days...:( Plus, I'm Throwing 2 codes P0108 and P0172. Well, I not sure what should I get for Tuning it...Since Avenger Said I dont need one...but I think they lied...I was wondering how about the Optimizer II from Kenne Bell (Not sure they will do one for a 2.5L) or Split Second FCT-1 with ESC ($569 Plus getting it tuned). IDK what to do...:( Any Guidance?
