If there is already a topic about this please point me in the right direction, I bought a duramax a few years ago that already had 5 tunes loaded with a dsp5 switch, my question is, can I change just one of these tunes without affecting the others? If so how do I do it? I have no idea how the tunes were loaded except that they used efi live, any help is appreciated
