I have my logs from last year on track (cooler weather though) with a tweaked 2.073 (reduced timing a little down low in the range that you can see the knock correction, MAF scaled, and that's about it)
I essentially never saw knock correction at high RPM. Just lift throttle (false knock IMO) and sometimes when getting on the gas quickly)
