The pressure came from the throttle shutting and really wasn’t there? I saw it happen on my gauge and it doesn’t seem like I’m hitting 30 PSI, but I have no way to tell. The only boos gauge I had was the Greddy Profec and it worked fine when I gave them the car. Another thing I noticed was the car never shows any vacuum? I am thinking it could be one of these things; boost gauge is broke; boost gauge hooked up/set-up wrong; it really is hitting that psi? Advice would be appreciated! Thanks guys!!
