ok ive got a 98 gtp, only thing done to it it "4 open cone intake (HAI) and u bend and cat delete. why im i seeing so much KR? i saw 8.3 kr today. the car is basically stock, are you suppose to have that much kr stock? And i know its real cause it only happens in high rpms when its floored. What can i do to help it? i personally think its the bosch plugs i have in the car....i didnt put there, came with the car, just noticed it. could that be what cause so much knock, cause of the heat range?
