Welcome back!! Boost and load actual look horrendous, and wgdc% is high. Could be boost leak but your ltft and stft aren't super negative, so if there is a boost leak I suspect it's not big enough to explain the extent of your under boosting. I'd check that vacuum is getting to your boost solenoid and if that checks out maybe look at your boost solenoid, as they can go bad.
How many miles are on your turbo?
