Looking at logs, the knock sensor appears to be wonky... It throws out random knock under little or no load and even under deceleration negative rel. pressure, teens throttle position. WTF???
Do forged pistons cause enough noise for the knock sensor to go off? Dropped my damn multiplier all the way to 0. Do they go bad?

False knock is a PITA. Never heard of forged pistons doing it (and those KB's are pretty quiet anyway). Usually it is something rattling like a loose or broken heat shield, or a loose part tapping against the block/heads/manifold. Sometimes raising the knock correction thresholds above the offending load or RPM can help.
Knock sensor is unlikely the culprit but I have one you can try out to see for sure.
This may be why you are running into the hesitation. When the IAM drops below .35 (or whatever it is set to) or feedback knock correction exceeds a set threshold the ECU will go to wastegate boost momentarily or until the knock goes away for a while. Also you can feel it when a lot of timing is pulled.
