when idling, you should be reading negative (anticlockwsie) as the manifold is under vacuum and the turbo is not boosting. when driving along, NOT boosting, you should see numbers, still in the negative, but less so than at idle, even aproaching zero...
then once you hit boost, the dial will swing clockwise, and start reading positive pressure. how much? depends what car, engine, and how youve set things up.
