A buddy and I were doing some tuning and I suddenly get knock at around 3500 rpm so I let off. I've done everything to try to chase the issue. Attached is a log of that run and everything seems ok. I'm stumped and don't know what else to check.
Also, it does it if I free rev it. If I ease the throttle it wont knock but if mash the throttle it'll knock.
