Hello All I am having this code come on about every 100 miles or so I had the car tuned and there is no pinging from what i can hear but i still get the code every 100 miles or so could it be a bad knock sensor? Also when have it tuned the tuner turned up the sensativity of the knocks since they are on the side of the block now. Have any of you had this happen with your ls2 motors? Or do you know what to set the knock sensor to when tuning

Thanks
