So did a review of the logs and noticed Dave was trapping Total Knock Retard. The one thing that was consistent was as soon as I started WOT, TKR went up -- the highest was 11.5°.

I'll wait to see what I'm told, but I'm guessing this is a 'new' issue and would need to check for:

A) Bad Gas (I fill it up each time, so that is not likely)
B) False knock -- something hitting the frame (exhaust, oil cooler lines, something) and vibrating on the frame
C) Noisy valve train -- engine sound fantastic, I don't hear anything obvious.

I can tell the fueling is better based on Dave's selected config. I'm leaning to B -- Exhaust was welded, new fuel lines and they are near the Hotchkis. Headers could be it since they are near the sensor.

May need to add some fire-sleeve around those lines just to make sure. Then, check and see if the exhaust is possibly hitting the frame somewhere.

I'll see what Dave thinks first -- 11.5° of TKR is ALOT, (seems excessive) since I don't hear any noise in the engine....
