While continuing to refine the tune on my supercharged G8 GT, I noticed that my WOT 6-3 downshifts are still fairly "sloppy." In stock form, they were absolutely horrible due to torque management, but I've tuned that out to a reasonable extent with TM set to use only timing control and a minimum TM spark of -3. This reduced the jerky motion, but the shift still takes a long, long time while it's pulling about 200 ft.lbs. through timing reductions. In the attached log at 4:01, there is a wide open throttle shift from 6 to 3. You can see that there is clutch control torque management being commanded by the transmission for nearly a full second while the shift completes. After this, it hits into gear nicely, but I'm looking for a way to reduce this shift time.

Unfortunately, there are no shift time tables for 6-3 power downshifts, so I'm trying to sort out the shift sequence to see how I can help the issue. Although the current gear PID shows it briefly cycling from 6-5-4-3 in the blink of an eye, I'm fairly certain that it doesn't run through each gear. I have reduced my 5-3 and 4-3 shift times in case they are an intermediate step, but haven't noticed any difference. It's worth noting that power downshifts from 6-2, 5-2, and 5-3 feel perfect, with 6-3 being the only problem child.
Can anyone suggest anything else that I could try?
EDIT: If it matters, I have reset the transmission adapts and fast adapts while at operating temperature, but it had effect on this issue.
