I did purchase the software and cable and a laptop but was unable to get the software up and running on my laptop. I may try again to install it as I wanted to lower the truck about 1/2 to 3/4 of an inch. I may end up having to take it to a shop to get it done.

Is calibration part of the installation of the bags? Or is it optional like alignment if you have a shop which has DIS do the job?
