(Seriously, I don't know why....I would think of you detonate, you are igniting TOO early, and most of the fuel should get burned up (no flame shooting)).
Generally, I see my knock count right around 20 during hard pulls.
It increases with RPM....used to be lower, but when I added higher lift cams and stiffer springs, it went up a LITTLE.
Every once in a while, I will see some knock in the 30s and VERY rarely get a blip in the 50s.
Sometimes, the high knock counts come during shifts and can be caused by piston slap (or so I have heard).
I only HEARD actual knocking one time, and that was bc I mis-calibrated my boost controller and overboosted like 2-3 psi above where my car was tuned for.

yeah mine will stay low sometimes and then under certain load situations maybe going up hill or something it will spike. DO not know if it is actual knock though since I can not hear anything sometimes. It has been smoothed out some from street tuning but I am in the central US. Not many people within 300 miles can even tune on a Power FC.
