Still the same issue.
I took a stethoscope to the motor and exhaust again to see if I could hear anything, nothing it of the ordinary.
I can tap on he exhaust and have it register knock, more so on the passenger side of the engine than the driver. I'm going to try to dynamat over the knock module for diagnostic purposes, simply to see if only one of them is picking up the knock.
If that doesn't work, I will maybe try another knock module, knock sensor (even though it tested fine) and then last resort maybe a new PCM.
I'm 100% certain it is false at this point, really good A/F when dynoed, does it with race gas, does it when not under load.
This is getting really old.
