    Don't change the VIN number unless you absolutely have to, it can cause licensing issues and you may not be able to modify the tune again.

    If your PCM is one of the Green and blue PCM's that have...

    There is another way to use a truck tune to manage the fans and the compressor. You will need to have the truck licensed, you will also need to get the A/C pressure sensor from the later model truck....

    You should be able to read that PCM with the scanner, you just can't make any changes to the tune.

    You mention that the distributor was worn and I imagine replaced. You can't just set timing on...

    More of what I meant was...

    A question first...

    Is the car running a stable tune? even if it isn't perfect?

    If it is, then you can hook up the MPVI to the car and "read entire" and save...

    My buddies 2001 Suburban with a 5.3 is drive by wire, yet my 2002 Silverado with a 4.8 is drive by cable. So you may still run into it.

    I don't believe you can swap segments with an OS mismatch. I would run the 2002 K1500 file that has been segment swapped to run the manual. You will need to make sure the new tune file (whatever you...
