John, a stock 06-07 STI makes about 220whp on a mustang dyno. So, I'd have to think it'd be higher than 230. Probably 250-260whp. I still haven't looked at my old dyno plots.
Edit: I was about 250 with a Stage II protune and 266 with grimmspeed 3 port bcs and perrin tmic. Granted a VF39 flows more. But, I didn't have any sort of headers/crossover pipes. So, it'll probably be near 250 on the smaller turbo.
