Yeh seems to be running clean at the top but just doesn't have the mph that it should. I'll be getting off my ass soon and making some changes and getting the tune looked at by a workshop that actually knows how to tune power FC's( PFC was put in by the previous owner and was tuned by a certain shop with a big v8 back ground) .
It's done 270rwkw on unigroups dyno at 1.2bar I never got a printout of the run but the guys there seemed to think that the curve wasn't too bad at all . hopefully after the tune is looked at , cam gears dialed in and a couple of exhuast restriction removed hopefully should be on the money . I'll let you know how I go , is your GTR here yet?.
