That's what scares me also. Is there anyway to be sure you have knock. Last week my tuner did some logs. Showed absolutely no knock anywhere.
In the audio u can barely hear it. And I know the exact in listening for an I can barely see it. So intel I fine a better way to capture this noise. No clip!
The runs and pulls like a champ. And this noise has been around for like 2-3 months. Hasn't gotten any louder. I did recently have some misfires recently in cylinders 3/4 due to my super conservative tune and temp drop.
