haha, a 3 week wait, but im back on the net ;p
I went and resplaced all the O-rings on the injectors, and I get no stumble/bogging under boost anymore. My VAC is still at ~9hg, so I went and ordered an intercooler, and some piping, along with couplers and t bolt ****.
Well, I got everything installed, cleaned out any parts I re-used (BOV is questionable, many miles on it and I think it may be leaking) and bolted it all down, and took it for a test run.
Now I get a horrible whistle in boost, and it has issues holding boost... AKA Boost leak ?
I'm thinking it's this BOV, but I went and taped up the VTA/Recirc Port, and I've still got the horrid whistle ;p Is it the vac line-bov that would be leaking?
Guess I'm going to make a pass over EVERY vacuum line/charge pipe.

Orings fixed ur Originall issue the bov is the source of your other issue probly or your IC piping etc. Is the bov closed fully when u have it sitting on the shelf? if it is just dont hook the vac line to it and it should stay closed leaving that out of your leak equation.
I did what you suggested, pulling the line from my BOV and capping that line end, and what do you know ;p The Gauge displayed ~20hg VAC
The whistle has changed
. It has now dissapeared, but the leak hasnt. No worries, I believe I've found the source, though. Ty for the help, will post back if I 'eff up.
