What do your boost targets and wastegate duty cycle targets look like the 100% columns? Your wastegate duty cycles are increasing towards redline as your boost is falling off. There could be a couple of reasons for this. I'm curious to see what your map looks like first.
Also, your car appears to be pulling timing in a few places (at 4200 rpm and then at 5000 as wrxblubayou said). It would be good to smooth out your timing curve a bit so that it's non-decreasing once you hit peak load.
Are you running on 91 octane gas?
Thanks,
Mike
