I started getting a little flutter on the vacuum gauge at idle about 3000 miles after the build. Ran some MMO through the intake and the problem cleared up. I now add 4 oz of MMO to each tank of gas and the problem has not come back at over 4000 miles.

I was a MMO skeptic and now am a true believer.
