its 200bhp@16psi at the wheels, had it on the rollers after changing my stage 3 head for another stage 3 head then booked it on the rollers, the tuner said the power is dying off top end to early and asked me if it was deffo cammed, an the oil light also flickerd, so i left an drive it home, next day oil pump died which killed the turbo by starving it of oil, so new oil pump, new turbo fitted, and now i have the problem above in my 1st post, i dont think its ring wear cuz i hav no smoke at all, an the engine sounds mint ticking over and underload hope this helps! ps. i noticed my dumpvalve is really quiet as well under load
