    7Gs with boost gauge

    What's your vacuum at idle? And whats your idle RPM?

    On my old motor, from the day i put the boost gauge on to the day it died, motor was always at -20vacuum at idle, ~900rpms. Now with the new motor, its -25, ~850rpms. Just wondering how varied everyone else's readings are

    A clogged PCV valve will increase your engine's vacuum reading.
