Anyone care to take a look at this log? Knock retard is pulling out a consistent 3.88* (spikes & falls down, spikes & falls down) of timing under WOT 1st and 2nd, fades out and doesn't do it anymore in 3rd. Commanded timing when knock comes in is between 21.5-23*. No audible ping can be heard. I also am using an LT4 knock module already.

I did find one tight spot where the passenger side header (collector area) was makin just slight contact with a metal "shroud" around some wiring when the engine torqued up, but haven't got a chance to log and see if that was it.
