I got a slight noobish question but figured this is the best place to get the answer. I have a '10 Sierra w/ 6.2 and I'm building a 6.0 for my ford ranger, I order the autocal and efilive program from Blackbear for my Sierra and was great! But I'm about to install headers and eventually a cam. So I decided it would be nice to slowly learn to tune on my own. I was just wondering what else do I need beside the program that came with the autocal?
