Had a question if anyone could help me out. I barrowed a friends computer with hp tuners and his interface to unlock my ecu in my Silverado. Paid credits to unlock and tune it for a cam swap. Now I'm going back stock and need to swap back the original file but his computer stopped working. So I was wondering what is need or how to use the interface on a new computer or how to transfer a unlock ecu to a new interface. Thanks for any help.
