Hello I work on diesel semi trucks I just purchased a labtop that had programs for cat and cummins that I use for work. When I recieved it I noticed it had efi live v4 pro. It I am interested what I can use this for if it is upgradable I am in to diesel performance so I have heard about efi programming. It also did not come with any cables what would I need to use this. Any info would be greatly appreciated. Thank u
