just got back from the dyno, after they detuned it from the e-tune from before it put down 380hp - 364tq on the 18g (w/ 10cm exhaust side and 3 inch inlet on intake of turbo). also have 1000cc injectors, STI intake and tmic. so you might be able to expect something like high 300's with a similar setup. mine was limited by what the trans could take as its still the 5 speed. if not for that I would be over 400 so I think you might be able to go far above me without trying very hard since your running the 6 speed.
