Edit: I am going to check for a boost leak over the weekend and if none are found will look into replacing my boost controller based on houtan's observation.

"boost controllor" is just the way JB4 is described because of how once you move to a "BEF" all the JB4 is doing really is tricking the DME into thinking there is less boost than their should be. It's more or less just acting as a way to control boost. All the DME logic is LOAD based though (unless you move to wgdc based tuning strategy). Being off boost target by <1psi is not an issue at all and there are no indications of a boost leak. WGDC is at ~60% to achieve 17psi.
