Under boost targets

Hi guys, just wondering if someone could take a look at a log for me. Car is a 11' FBO and JB4 w/ MHD BEF. Seems to be undercutting boost targets by a good 2-3psi. Happens in every gear I log in.

Updated my jb4 to the latest firmware about 2 months ago. Did I need to do anything with the diode before I updated? Not sure what board I have, but purchased the jb4 6/17. Trying to figure out if it's a hardware issue or just something with the jb4 and/or BEF.
