Re: Vaccum during boost?

Vacuum at idle should still be around 19" to 21" depending what kind of shape your motor is in. My z6 idles at 20-21" idle is at about 900 rpm.

I noticed with my car that after I adjusted the cam gears the vacum at idle went from 20 to 16. And when I put the camgears back to 0 the vacum went back to 20" hg.
