SO I need to tune a 07 5.9 automatic for a customer remotely with an autocal. is there a way to select the right OS for his vehicle with the VIN number or how should I go about this? just set the auto cal up to tune his rig and have him download the tune and email it to me? and then send him his tunes back and show him how to set them up? I'm thinking that's the right way to do it in this case. he won't be home till sept from japan and this is the last thing I have to get shipped to home. thanks for the help.
