Those don't look like stock spool mode cutoff RPMs or maybe I don't have the resolution to see properly on my phone. Have you modified this bin? Part-throttle isn't as easy to diagnose as WOT, but boost mean goes way over target there, which would result in a throttle closures just like WOT. VANOS can change drastically between spool and cold/warm running tables, especially cold, and has a big impact on boost and calculated boost and, thus, load, torque, etc.
In spool before shift, out of spool for shift, back into spool after shift would be expected to cause larger spreads (less smooth) on parameters (MAF, AFR, VANOS, timing, etc), but I don't really see WGDC responding to spool mode, maybe because of the boost overage already in place.
