I know that the vacuum should be at 20 in.Hg at idle, but with my car its around 10 in.Hg. I do have cams, but they aren't anything too aggressive (264 in/ex step 1). Sometimes the vacuum goes below 10 in.Hg during idle. The only time I see 20 in.Hg is after I give it throttle and the RPM's go 1200-1400 then it drops to idle and so does the vacuum. It never really bothered me until the other night and now the problem is just annoying me. I am going to do a boost leak check in a little, but are there any other things that I should check?
