lachlanw Posted August 15, 2011 Share Posted August 15, 2011 if the ecu is tuned for it you could run 18 psi rb20det standard runs 10 psi . front mount plus exhaust will usually get it bout 13 . so run at least that . was the ecu re mapped with a 34 turbo or the 20det one ? and yeah get a real boost gauge . is it plumed up properly ?

lachlanw Posted August 16, 2011 Share Posted August 16, 2011 just re read your post you said you connected your boost gauge to the hose for the factory gauge . did you join to that hose or run your boost line to the plenum? . that factory hose is well known for splitting and leaking at the plenum end check that Link to comment https://www.sau.com.au/forums/topic/374123-r32-gtst-boost/#findComment-5968985 Share on other sites More sharing options...

Sarumatix Posted August 18, 2011 Share Posted August 18, 2011 definitely a vacuum leak somewhere.. would put money on it. Had similar symptoms, turned out to be a badly plumbed boost gauge.
