AND if that is correct then it sounds like it is a waste to mod until the knock issuse is solved.

It depends on the situation of course Baylor like with anything. But conditions the same the dyno should not produce more knock. In my experience I have seen more false knock situations on the track rather than the dyno. Thus why I go to the track OR go on the street with every vehicle after completing the dyno tune to make sure that there is no variation.
We do know as per your personal car, the car just did not want to go past 6k on the dyno but I've dyno'd probably 10 or so other V6's without a problem. We also know from logging that in first-second gear your timing is higher than third gear down the track. I cannot log the actual KR, but I can log timing advance. From looking at the timing in first-second, comparison to third it does seem that there is timing being pulled possibly from a resonance from modifications?
I do know that I had a tune completed for a 2012 LFX making 341rwhp thru auto, but was missing the proper torque tables to have the car brake stall properly, so I had to send my tables outside and have a tune performed via email with my parameters, and that the knock sensor tables from my tune could not have been used because I had 0 knock, next time down the track with the other tune in there it was pulling 10+ degrees and going to -7.5 on the shifts.
