miko_supra Posted April 16, 2008 Share Posted April 16, 2008 sounds like it could be a dodgy vsv. Do a search. right the car is full bpu and was boost in 1.2bar when it went in to him now it only gets to .8bar it went on the dyno and made 404bhp which i was nt inprest by BTW why were you not impressed with 404bhp for BPU? seems pretty good to me Link to comment Share on other sites More sharing options...
