OK I have efi live and I love it! Robs Built tranny tunning is awesome! My buddy Just got a LLY and wants a towing tune. Can I tune his truck too? I dont know how to seperate the tow tune I have because its in dsp format. Would he have to buy It from Rob? Also would he have to buy a vin license? How much would this be? He doesnt want to spend the big bux for the V2 and all he just wants a better tune. Please help.
