    Well, I'm sure glad you shared THAT with me.

    The job of the blower is to pressurize the manifold, so it's only natural that you'll have less manifold vacuum at idle than a naturally aspirated motor. Hook a dual-function vacuum/pressure gauge into the manifold and you'll be able to see it go from vacuum to pressure as you come up on the blower.
