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" you might want to look at my post on 08/27/15 at 01:24pm... 7th from the top.
I do not put my Allison in N while moving and I did not miss your question nor the edits to your post.
