Default ????? About Knock Modules

Im assuming the LS1 has a knock module as do the LT1's. But i was wondering, i have a 2000 M6 Z28 and i can drive down the road and pull it in 2nd or 3rd gears and apply a little gas and feel the car kinda stumble. I like the car looses timing or looses power a little. I have pacesetters and other bolt ons. Just didnt know if the knock module maybe pulling timing and this is whats causing my problem.

could be possible. False knock is likely too with aftermarket exhaust if its hitting anything.

Without a scanner hooked up, it's just guessing.

I don't recall where they are located on the LT1, but on the LS1 they are under the intake, 2 of them. You need scanning (HPTuners, EFILive) to see what is going on.
