Does the sound come directly from the engine or would I hear it further back if it was a knock? And I'm not sure if this matters or not, but I tried just doing a rev while in park, and it makes no sound in higher RPM.
If it only does it under load, it very well could be knock. Datalog your car and send it to Lund so he can look at it
