MAFT/S-AFC Tuning advise

That is great news! If your tune/AFR's are fairly spot-on, then it might just be "phantom knock" or the sensor going on the fritz.

I might try to just replace it and see if that helps. I read on here about a guy who had Phantom knock and it was his wastegate flapper rattling since they welded the arm and not the flapper when he went to an external wastegate setup. I might have to check that as well as mine is welded shut too!

It's just an erratic reading, knock I heard is usually progressive, you don't get knock, then zero, then back up to 20+ get what I'm saying? So I'll be keeping you guys posted, but I might try a new sensor just to be sure.
