    C0558

    Anybody get this configuration code after tuning a '05 or '06 truck? Won't clear and I tried to reflash the pcm and get the same code back. It's a hard code that sets as soon as the key is turned on.

    GM SI states to program the EBCM, but since I never replaced it or flashed it I couldn't see this being the issue...
