ok, i have a friend that already has efi live. we both have LB7's. He said i can use his vin if i pay him for it. We both want to get setup with the Dsp5 switch and run the same tunes. All the tunes are there, we just need the switch. Also, i have no idea how the dsp swithes work so how dowe make it work?? What do we need to do?? Thanks guys!
