Tired of it trying die when I lift the throttle - especially after a blip when not really moving ... who knows the vacuum system and can tell me where to check?
Thanks... -------------------- ... she likes bein' forced ...

Evo's FP is like 43.5 stock at idle and I understand w/the walbro most run about 50. Further, almost everyone that talks about it (EvoM) discounts that it's a problem on the Evo.
So let's say I get an FPR and do install it. Can it be installed in such a fashion that it's just a gauge so I can read her before adjusting it? I know it needs to be a 1:1 in order to increase the pressure as boost goes up. But I'd like to see where it's at and dial it back slowly to see if I can fix the problem. I'm assuming dialing it back is dangerous without a re-tune so I'd rather be REAL cautious. Also, apparently HKS includes info w/their cams about bumping the idle screw and fuel maps for just such problems post-install. My idle runs around 900 when good and warm and I'll likely try the bump. As far as the BOV is concerned, I hear Works' is good as well - and I already have a relationship with them. Perhaps I'll call them up - I can even ask about both issues. Keep the ideas coming - I'll keep posting updates. Thanks all! -------------------- ... she likes bein' forced ...
