yup i know it really only works at WOT, or when ur car is in a cold start lol. today i heard a ticking sound comin from my motor, i checked the code, it was a knock sensor code, cleared it, and the motor stopped ticking. so now i am really confused. but im gonna change the plugs tomorrow anyways just to see if it works to my advantage. i still got my stock plugs so i will use them first.

i will shoot back!
