Looking through my last scan, I see 69% duty cycle at WOT. I wouldn't think that's a problem.

Nope. Wide open all around. I even have enough room between the rear O2 and the tunnel to get my fingers between them. I'm fairly certain my motor isn't moving that much. Solid motor and trans mounts, flipped dogbone bushings and poly dogbone inserts. She's solid.

This seems more plausible. The high knock I was seeing was on stock trans settings. I've been playing with them in the tune. I need to make another log. Not buying that's my biggest issue though...

From all the reading I've done about this, "burst knock" seems the most likely. For me the solution is simple: Just roll into the throttle. No more knock. I'm talking less than a half a degree from 0 to WOT, through the shifts... Besides, stabbing the throttle just results in a bunch of wheel spin anyways.
