Autocal help
I just received my tunes from Justin and loaded them (87oct,93oct, and trans) to the autocal, plugged it into my tahoe and loaded the 87 and trans. A few hours later I needed gas so figured I'd get 93oct to see its potential. Did/do I need to delete the 87 from the autocal before loading the 93...- Speed856
