Well I have my aeroforces hooked up and holy KR, I got 5 degrees at WOT, not too impressed. The ONLY mod I have done so far is a CAI. Need help guys. I have headers and exhaust but that comes later on this month. Would using colder plugs help get rid of some of it until I get them on? I know L32's are more prone to knock but damn 5 degrees? HELP!
