Think there must have been a very generous operator Mikkers.
TD04 peaks at 5500, must be boosting 1.7 -1.8 peak for that sort of bhp, way outside the safe zone.
Mine was boosting 1.6 and only making 256bhp at the fly. Now makes 253.5 at the wheels(318 at the fly) on vf34,550, sport 3"downpipe, sti intercooler
Not sure td04 can get enough air mass in, normally top out at about 280-285 on a very cold day.
Would love to see the print out of the figures.
