From what I've been able to gather the increase is based off of 320hp/370tq... +8%/+6% which is 345hp/392tq. That's with Cobb's Stage 1 aggressive map which means you're fully stock and running 93 octane or higher vs. regular Stage 1 which is 91 octane. I have been unable to get any numbers for gains on just Stage 1 running 91 octane. I was talking to Cobb and last they said they were digging through dyno's trying to find one, but I'm not holding my breath. As it stands I just don't think Stage 1 is worth the minimal gains. Probably not worth it unless you start getting into Stage 1+ and higher; unless someone can convince me otherwise.
