I also sometimes get weird dips in my boost in a 4th gear pull, which dont appear when i do 1-2-3-4.
Your WGDC also looks very high for being below target boost. I am seeing in the mid-high 90s at points. Are you EWG or PWG? WGDC that high and being below target boost could be a boost leak. In my case, my WGDC isnt crazy high (low 80s), but yet i am still not reaching target boost.
Another thing that looks odd to me is the Load act vs target. Maybe this is different for BM3, but i thought your load actual should be way closer to load target, especially when you are off boost by only a few PSI. In my MHD logs, the discrepancy between Load act vs target is much smaller and pretty much only occurs when i have boost below target (as expected).
Also, this is probably just a BM3 thing but your boost target curve is totally flat whereas mine is variable in MHD.
Some of my logs and discussion is here, but not apples to apples since i am MHD:

Thanks for the description, I have plenty of logs where I am hitting target boost if not +1psi higher. However my WGDC has always been in the 90's since I flashed any of the tunes.
I sent PTF a message about the WGDC and not hitting boos targets. I'll see what they say and also try pulling a few more logs to see if I am hitting target now or potentially have a boost leak. Sometimes I feel they don't review the logs super in depth or maybe all of these things are non-issues? I really am not sure.
I am EWG.
