Time to get HPTuners and a wideband.

Or try a bottle of some quality octane booster and see if the knock goes down, if it does, the knock is real, if it doesnt, then its false.

I'm selling my wideband for the sole purpose that I will never have the time to learn how to tune. I run 94 octane fuel, so there is still a possibility the knock is false. Could the transmission dipstick rubbing up against the headers cause false knock?
