Lane5.9

Thank you! One last question? Do I just unplug it from truck upload itvto the box then plug it back in?

I'm new to owning a cummins I purchased a 2003 5.9 quad cab, and it has a quadzilla max milage and a pv1 monitor on it. The guy told me I could download a xzt tune for it, but I can't find it anywhere. If anyone knows anymore or has the files please email them to me or inform me on what I need to know. Thanks!
