Even stock cars can have numerous amount of codes, esp with a failing HPFP and such. Defend your warranty get the codes that they are trying to deny your warranty with that directly link the JB3. I really cant see the JB3 throwing any codes when some members even rn Map6 o 91 octane without any issues, unless you did something we dont know.
P.s. i have heard some members on stock cars throw superknock codes.
Pretty heavy modded car could have throw codes from differenty mods that were put on.
