[QUOTE="IUP99snake, post: 11573531, member: 7060"] Thanks for the advice. I think a good vacuum amount for it to open would be anything higher than 5 inches/hg. That'll keep it open at idle (20 inches) and also during freeway cruising (10 inches). I'm gonna take mine off and test it with a vacuum pump to see when it opens up. The problem could be the vacuum source I'm using. Right now it's T'd near the boost gauge, which is also T'd off the vacuum hard lines at the back of the intake. I should probably use a dedicated vacuum source for this. I think what I'm going to do is take the boost gauge and BOV lines from the other vacuum hoses and use a dedicated source for just the two of them. I'll probably run a vacuum line straight to the BOV and then T off of it near the BOV and run a line back for the boost gauge. That way I get an accurate reading of what exactly the BOV is seeing. I have some idle surge/hanging issues, and I've always blamed it on my BBK throttle body, but I think it might be caused by the BOV not opening at idle. There's a lot of air moving through, even at idle.. I remember my stock procharger valve used to be like a leaf blower at idle. With nowhere else for that air to go, it could be causing the idle problem. A good way to check would be for me to just pull off the BOV, plug the line, and do a test drive with it open and see how it behaves. [/QUOTE]
