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

Dang Larry, I only see 99MPG on my Silverleaf. I gotta find out what's wrong.

I think what you are seeing for boost during break useage is normal
