Should I retune with a reputable tuner and a known octane number? What tuner do you recommend if yes?

well the tune is in your computer, to get that engine going you will need the 2 bar MAP your car knows. there are two go to tuners we are down to, AJP, and GearHead. search the forums for the contact info for AJP - Brad. GH has a website, and will NOT do off road tunes. AJP specializes in turbos - period.
