    youre pushing it when the converter is locked? if so that is your problem. let off the gas then ease back into it.

    What are you using to check for KR?

    It sounds like part throttle KR (aka PTKR). Some also call it burst knock. Took me months of tweaking my file (and a lot of playing with the TCC settings) to get rid of it. I can lean into it up to 40% throttle (which is near a 100kPa on the MAP) with the TCC locked in overdrive and have no knock. Get to feel that brute force torque of our engines.
