i'm gonna guess its fuel related.

is it possible you have a vacuum leak somewhere? i'm gonna guess the car is running lean and thus knocking because it looks like you peak torque timing target is about 14 which is not too aggressive at all.

your wastegate is maxing out too. maybe something mechanical, it shouldn't take 100 percent duty cycles to run 10lbs of boost at redline.
