I finaly got around to replacing the broken BCS. It was all cracked and didn't seal correctly (must have been a large vac/boost leak).
When I had the stock BCS in the car would boost up to about 16 PSI independent of the fuel switch. I did notice a chattering sound when I let off the gas after reving the engine or coming off boost quickly.
I installed a manual boost control setup. For now it is functioning as a standard Gilis valve. I set everything for basically 0 psi(bolt all the way out), double and triple checked the plumbing and went for a drive.
I was expecting 10 ish psi (what I've heard the WG spring is rated for) but instead got about 18. I'm not sure if it would have gone higher but I didn't want to push it. When I let off the gas there was a brief whooshing air sound similar to a blow off which I can only imagine is boost leaking around a coupler. The chattering sound is still there.
The plan for tonight is to hook up a small compressor and see if I can get the WG to move. I may also throw the compressor in the back seat and see if I can hold it open while I drive (should see 0 psi on the gauge).
I've also been using the notorious stock boost gauge, I'll setup something more accurate tonight too.
From what I've searched and and read on the forums the boost does seem to be coming in later than average.
Where should I be boost wise with a stock setup at various RPMS?
Any thoughts about why the WG doesn't seem to be actuating?
Anything else to check?
