Well ****! lets try the higher octance first, if still present then gotta look at common things that will cause a "knock" (I'm sure you already have) carbon deposits, loose mounts, loose tc bolts, exhaust hitting on frame at WOT bc of loose mounts, electrical wiring, BAD PCM(may be not) after that...... teardown I guess!

Let us know what you find

nothing is making any noises. I HEAR NO KNOCK! How much timing do you think a 10.6:1 motor can take on 93 octane?

I'm also noticing if I have my log file open and it says like 23 degrees of timing whereas the corresponding cell lit up in my tune says 20 degrees. WTF
