Okay... I've got a 94 intercooled procharger set-up that pushes about 9lbs. It was already chaged when i got it. When i got to looking at it, i realized that my blow off valve vacuum lines were blocked off. Well i ran a line down from my intake to valve. Well there was two vacuum lines there. Well from what procharger says there should only be one. I got to looking and it says hks on it. I looked around a little and found that i have a bypass valve instead of a blow off. It seems to work somewhat but it seems like it doesn't want to work until about 3000 rpm. My question is, where does the other vacuum line go and would i benefit from routing the air back into the intake instead of blowing it into the atmosphere. Also, anyone have an oppinion or experience with a bypass instead of a blow off valve. Thanks.

kinda wierd its not working till 3 grand, considering unlike a blow off, the whole point of a bypass valve is to stick open a little and not put so much boost and stress on the engine when ur idling, so id definitly have to say its not working right with whatever way the other vaccuum line is set up the one you dont know where it goes
