Excuse my ignorance but, can I buy EFI Live for my H2, and when it comes out for the 04s, use it on my truck? What all would need to be purchased? Just a license?
You can do that, as long as you get the new v2 (blue one) with both gm and cummins tuning options. Or gm option now and cummins option later when 03-05 tuning becomes available. That is if you want to have your own v2, instead of just having them tuned by someone. So many choices.
