It would be hard to judge the power just by the list of mods. Assuming he's on stock ECU and turbo, and 10-12lbs of boost. I would guess in the 250-260ish, but that could be way wrong. We need some track numbers or something to judge from.

With those mods, the only thing that matters is boost level. If he is running 12psi (the accepted max pressure on the stock turbo for reliability), he has 275-280hp tops.

I managed 277rwhp and 252ft lbs on 11 psi. Just exhaust, intake and FMIC.
