I took it to the track and ran a 12.2 @ 116.25mph with a stock ECU, stock boost, 93 pump gas, 19" HREs, and some mild exhaust work (I still have two out of the four cats in my car, so all I did was remove two cats). I'm basically bone stock. The exhaust gains were minimal given my wheels. The heavy, 19" wheels DID NOT help my times and easily cancelled out the gains from my exhaust. I drove it down there, ran low 12s on a hote, 88' day and then drove it home.
I can at least say that I have one of the fastest, stock cars on IA.com. I don't have the time to sit and invest in having one of the fastest "modded" cars on IA.com. I'm content...
