Knock Counts Seem High, But no Audible Knocking

See attached datalog.

I have tuned out the knock retard for performance sake, and I have since modified my tune to take 1-2 degrees out at the points where the highest counts are per Dave's spreadsheet for WBO2 tuning.

Background, Stock L31 Longblock w/ Performer RPM and TBI adapter. Running ~ 18PSI of fuel pressure. Nothing special. Pulling the timing at the points where I did put the timing table at those points about in line with the Stock 98 Vortec timing table available on this site.

Does anyone have any suggestions on this? I am using a stock knock sensor and ESC module for a 95 TBI Suburban. I have read before that these may need to change for roller cam? Also read that perhaps over tightening the knock sensor (which I replaced) could cause false knock?

Dave suggested I may have an issue with my distributor, can anyone else confirm or has anyone had a similar issue?

I'm also getting knock counts and retard on my roller Vortec TBI build. Power is down, too. I built it in '11 and the power recently dropped off.

The weirdest thing is my log shows 10* less than my table in the bin, and I have the main spark bias set to 0. I had a code 43, but the resistance on the sensor and volts on the wire tested perfect, so I turned off the code. I'm wondering if the ECM still "sees" the code and retards timing.
