7-14 psi turbo boost when engine compression brake engaged

With an engine compression brake, there is a LOT of air flow through the exhaust side of the turbo. Remember, that is how an engine compression brake works-- it opens the exhaust valve as the piston approaches TDC on the compression stroke.

As usual Brett, you're right on. But, on an "Exhaust Brake", there is no flow or, maybe I should say, absolute minimum flow, correct? And, if there's no flow, then you can't "Build" pressure enough to show on the turbo pressure gauge, correct?
