I'm getting knock only when I go into PE mode.

I've noticed that I get slight knock retard as I roll into the throttle and go I'm guessing that it's right when I hit PE mode. It's not a lot of knock, it's like 1.5-2.5 degrees and decreases quickly as I go up the rpm range. I'm posting my tune when this log was taken, and I've already adjusted the VE table as it was lean in the range. I've also captured a screen shot of the actual spot I'm talking about. Any help or advice is appreciated.
Thanks.

I put up the tune that was in the car when I logged this, as well as what is currently in the car as well as the cfg file.

Again, the only time I see knock is in the 3500-4500 rpm range when I am rolling into the throttle.
