Definitely easy to try a flash, but I wouldn't do v8. They're just as jammed up on requests as stock, I'd try a v7.

I have no similar issue on the stock bin, but I'm also on a 3.5 bar TMAP and don't have the constant mean over target that you do, mostly only on shifts and immediately drops after shift. Your spool mode is definitely odd though and not helping.

Your boost mean is going up well before throttle closes, it just goes up more when throttle closes. Your boost target does go up there as you press the pedal more, but not as quickly as real boost does.
Couple things you can try:
- Flash the stock map with linear throttle option
- Adjust the torque request in that area
- Modify the MAP conversion
- Reduce WGDC adder in that MAF range
- Retard intake VANOS a bit in that area
- Can dumb down the throttle closure response a bit, but no reason for it on a more dialed in setup
