hi all

2003 impreza sti type uk

owned from new, ppp was fitted at dealer the re mapped at prosport in stockport @350bhp, other than that bog standard

ive lost pulling power after 4k revs, turbo spools but feels like no power after that, and a smell of petrol. feels like it cant breath properly, the hard pull has gone

so ive narrowed it down best i can

should the wastegate actuator physically move when reving the engine, because its not, i can move it with my hand so its not stuck.

does it have a boost control solenoid?

also seeing as its 20 yrs old and had a recent top end rebuild ( head gasket went) when ive sorted the boost issue is it worth getting a fresh re-map?

Would be worth checking the map after all this time, a decent specialist should be able to do all at the same time (check over etc).

 

Boost solenoid failed or vacuum leak.
