A friend of mine put down 346 rwhp / 770 lb ft tq with only the free mods done to it. Its a '96 just like the one in my sig. I have yet to dyno mine though but I know its got to be more than his was.
Those numbers were with the fuel plate out, starwheel cranked, and the wastegate disabled which are all free mods and there is actually more free mods you can do to get even more than that.
Everthing else was stock, so that kinda gives you an idea of what you will make with turbo, injectors, dv's, etc and the free mods.:thumbsup
