    Hi everybody how is it going. I am looking for the ADX and XDF files I need for my truck to start my tuning.

    The 1998 K3500 7.4 liter is OBD2, which is not supported by TunerPro RT.

    I had been doing research and flashing the program isn't possible but reading data and changing the program file seems to be. It looks like I just need a flash program to load the file back in. Correct me if I'm wrong.
    I am a Mechanic not because I own a BIG Hammer. Rather, I am a Mechanic because I know Where, How hard, and How many times to hit it.

    I was a little outdated with my first post. TunerPro RT has "TunerProELM327_ReferenceV1.adx, which requires the ELM327 plug-in for TunerPro.

    That's no problem. I'm just hoping I can figure all this out. And make it the truck it deserves to be.

    One option, not really a low cost option, would be upgrade the "Black Box" computer to the new LS computer and use EFI Live or HP Tuners software / hardware to flash and tune with. Here is a link to upgrading the "Black Box": http://www.gmtruckcentral.com/articles/12200411.html
