    Default New to me truck with EFI Live HELP!

    I just bought an LLY that had been tuned with EFI Live with the dsp5 switch, it didnt come with the autocal, do i need to purchase a new autocal and tunes, or just the autocal? i need to change the tire size and just want to get my hands into the tune info, any help is appreciated!

    Best chance for the existing tunes would probably be the previous owner. Even if you got your own V3, I don't think you could read the existing tunes out (although that could just be the LBZ/LMM... I don't recall if you can read a 04-05 LLY DSP5).
