I need help here. I have a TurboXS BOV on the atp UPP and the AGP Blank off plate for my old relief valve. But my BOV still flutters under low boost. Even at high boost, it has the familiar hiss that turns heads :hahaha: but then it flutters right at the end. I was wondering if my vacuum lines are hooked up wrong or what?? I can't figure it out.
