Got a bit of a technical problem with a s14a and thought perhaps someone might be able to help on here. The car has an apexi avc-r fitted to it and a hybrid fmic but otherwise the engine is standard and im struggling to set the boost controller up properly after it was reset - it intermittently holds back at about 4.5k and the boost is really hit and miss. Sometimes it pulls really well but yesterday a saxo was pulling away from it (which must have been modified cause it wasn't hanging about by any means). At idle it has the VVT rattle which goes away when you put it into gear and touch the throttle - could this be causing the power problems? Also - sometimes you can hear as the turbo starts to spool up what sounds like the BOV dumping air really quickly - any ideas what this is? I didn't think it could be the BOV as when it does it the boost is just starting to build so it's only at around 0.8 bar - but when it pulls really well it will hold 1.2 bar fine?
