    idk, did you order a tune or tuning yourself, to me it would seem that having matching VINs on the ECM and Truck would be a good thing to have.

    What PCM did the 4.3 use? Probably not the same one as the Esky.
    I think you mispoke about using the V6 ignition system, not sure what you actually meant.
    You can't really just flash any VIN you want anyway. The VIN and OS pair has to match. The V6 VIN won't match a V8 OS. It really doesn't matter, it will run with any VIN.

    He is trying to change the VIN on the V8 PCM to the V6 VIN. Won't work.
