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.

Are you on a stock turbo? That seems pretty normal. You should upgrade your turbo if you want to make more boost up top.
