    What does the truck have in it now, is it a 4.8? If it's not, you'll either have to tweak this base file to suit the truck (VE, MAF, injectors, spark, transmission, ...) or get a factory-fresh file for it using SPS. I know for a while, some shops were selling base tunes where you pay a fee (was around $50 IIRC) and they'd use your VIN, flash a controller via SPS, read the file out and email it to you. I don't know if anyone is doing that still and I dont think I have a 1MB LS1 PCM lying around.
    Yeah, it's a 6.0 / 4L80e -- The closest thing I can find is from an H2 but was modified pretty heavily.

    I might just tell him he has to go to a dealer and get the update(s) done before I can do anything with it.

    I have a mildly modified (TQ reduction, shift points/speeds etc) tune for an 07 classic 2500 HD (6.0/4L80E) with the 248 OS you're welcome to if you want it.
