Sounds like fun!! Initial feedback is that you should do the upgrades incrementally. I am not sure I would recommend jumping into the 3.8 immediately, unless you absolutely know you want that level of power. Suggest getting the suspension setup right first, with cup parts and Motons/JRZ. Then do exhaust, headers and chip. If you strip it I think you will find that it has tons of power and you will be equal to track prepped 997 S's and hanging with stock GT3's (depending on driver ability. of course).
