Moving this from the General forum since I'm starting to go down the rabbit hole a bit more...
Seeing knock in 2nd. Ordinarily, one would expect this to be a fairly linear fix: reduce boost or reduce timing. Thing is, when I see the knock, I also feel a slight rumble... it almost feels like blowout. It's not like hitting a wall like when I was losing an injector, but it's noticeable. The question is that when I see knock, it's only 5-7 counts, so would I really feel that in the car? I know it's a question with many answers based on many things. Just looking for heuristics.
My vitals are: T3/T04 running ~21 PSI. I've already gapped my BR7ES plugs down to 0.022, but I can certainly go lower. 92-oct gas. plugs look good out of the car. Resistance on the 16-month old NGK plugs looks good. Didn't test the coil. ECU had it's caps replaced years ago, so that should be fine. I mean could it just be that I'm feeling 7 counts of knock? It seems like such a low knock count to actually feel...
Logs @ the link below. Pulls done on the 27th had new SD table values to clean up a slight lean condition @ WOT that I was seeing on the 26th.

Thanks!
