It might be worth looking on the mk5 forum.
A guy on there had a similar set up but may have changed the turbo now.
I wouldn't get hung up on figures, it's pub talk, if you need a figure look for the one at the wheels. Fly wheel extrapolation you should expect easily 340 bhp.
My edition 30 has autotech pump, panel filter, revo stage 2 and the blueflame turbo back (3 inch) being fitted next week. mine is currently b6t5f9 and according to my revo dealer is one of the quickest he's been in but I dont have any figures. Mid/top end is astonishing.
