Knock under 0 boost

[Polyol]

Occasionally I will get knock under 0 boost with no pinging sound. but my knock sum gauge shows im getting knock. When this happends I can let off the gas then hit it again with no knock. just wondering if anyone else has had this problem

Nope, you're the first one!!

Haha, just kidding. I would check for lifter tick. What does your AFR's look like when it's doing said knock?

 

[Polyol]

No lifter tick. replaced with revised lifters. afr is fine do to my keydriver stage III chip witch kind of ignors 0 boost knock at low accelleration

Phantom knock, Check and make sure your knock sensor is snug against the block...Maybe try a new knock sensor
