Re: Prochrager problem

Always hook the BOV after the throttle body blades, not before. Tee into a source back by your fuel pressure regulator and try your test again. The BOV opens under vacuum, not boost, so hold a vacuum gauge on one hand and open/close the throttle with the other while filming. Depending on the spring being used, you'll target Hg just above idle vacuum...

Edit: Nice choice with the BOV by the way...
