So I replaced the turbo inlet pipe (old one was torn) also replaced some old brittle vacuum lines (running from wastegate to manifold etc.) and also I had to replace the power steering pump.
OKAY, heres the issue, I was seeing about 11 PSI prior to repairs, now i'm only seeing max 9.5 PSI. I have a basically stock 02 WRX with borla cat back. Also there is a stupid effing BOV from the previous owner which is of course not re-circulating (dont ask me why)...
I am not quit sure what stock boost should be (i've heard a few numbers thrown around)
I suspect it may be either the restricter pill is gone - If so, would this cause boost to not exceed 9.5 PSI??
OR maybe a faulty BOV and it's opening premature??
Also, when at a stand still, idling, when turning my steering the vacuum seems to go to -10 -- Is this normal?? and what should stock vacuum be?? (-15?)
