Try clearing your load control and related adaptations. Side note, I'll get around to adding the pid timer tables one of these days.
Your gear change shows in the log around 300rpm before it actually shifts. Is this common in logs for AT cars?
Always been this way for me, especially the more power I make the longer it takes to shift. My trans is barely alive haha.

MAF axis on your BLM only goes up to 328 - isn't that the stock value? Not sure if it matters since it's linearly flat and extrapolation to 500+ would still yield BLM=3.0 I have mine going up to 500.Looks like my load limit multi isn't stock(can't remember where I picked that up from) and my torque max is stock.
BB version 3 so wgdc 1 is inverted with wgdc after PID. I don't log wgdc 1 to avoid confusion. WGDC after pid is my final output.
See below.

I’ve been having this same problem in the last few weeks with my WGDC AFTER PID value suddenly going to the WGDC BASE value during a WOT pull in the mid-5,000 rpm range so my total WGDC Bank values drop 15-20 points and I lose lots of boost (like going from 22psi to 13 psi at 5,000 rpm). It’s like there is no WGDC PID correction factor being added to the base value, hence I refer to this below as “WGDC PID zeroing”.
Strangely the WGDC AFTER PID stays at the WGDC BASE value for the next series of pulls. See logs below. It seems like some kind of error flag not resetting or something. This phenomena is also replicated in both my 93 octane tune and my new custom Flex Fuel tune that’s based on this 93 octane tune.
Below are the logs. Each datazap link has three logs. The first log of each shows the WGDC AFTER PID value starting off higher than the WGDC BASE value, but then in the mid 5,000 rpm range it drops to the WGDC BASE value, like there is no additional PID amount being added to the base value. If you then look at each of the two other logs in these datazap links you’ll see WGDC AFTER PID is identical to WGDC BASE for the entire runs.
Any ideas?

I’m not sure if this log shows a boost leak such as due to BOV (or in my case Forge diverter valves leaking).I had the same issue.
Checked for boost leaks found nothing.
Lowered the blm and worked around the issue.
Recently decided to rebuild my BOV. Now it’s overboosting.
BLM is now back up where it was before.
In short - my BOVs were not able to hold the boost as the internal seals were worn.
Those things need to be service once every year or 2...

I still have not figured out a solution to this. PID will eventually time out and boost drops about 3 psi. If I raise base it will overboost the whole pull.
Darn. I ran into the same issue recently, but I had my wgdc very low and was using BLM to cap my boost. So in a way I did it to myself. I wish the weather wasn't so sloppy.
