7-14 psi turbo boost when engine compression brake engaged

With, as always, zero torque and 256 mpg as shown on silverleaf. Anyone have any ideas why this would occur? I wouldn't think that turboboost should activate with engine compression brake engaged? TIA

A. H., look at the bottom of my post and the OPs. We do not have C brakes... just two stage Jake brakes. You now rate this :S and there is a BIG difference between a DP and PU.
