Default 04 Ram 1500 Cruise Problem

New tires on 4x4, used Superchips Flashpaq to change tire size to 35 inches by the manufacturer specs. Test drive and cruise doesn’t work now. I felt the speedo was still wrong. I down loaded a speedo app and checked it against my truck speedo to find it was 5 mph too fast. I feathered my tire height down to 33.24”. The cruise started working, the speedo was now corrected, and shifting was a lot better.

A known problem with that tuner, water your money sadly.
