Merry Christmas guy's n gal's. I'm thinking of updrading to efi live and so is my friend ( he has an 08 LMM ), we were wondering if we had to use our laptops , because it looks like a handheld programmer and they say it comes with 2 tunes and 2 licenses so you can program 2 trucks, can we just use the tunes it comes with, if so what are the HP levels and what can we do with the transmission tunes. P.S. please give me some detailed feedback thanks and Happy Holidays
