I have upgraded from my Valley Industries Odyssey controller (Prodigy knockoff) to the factory integrated brake controller.
It was only $30,000 dollars for the controller upgrade.
I like the feeling of the braking ability for both city streets and highways on boost level 7, but that does not translate into a prodigy number as far as I know. I determined boost 7 by trial and error and gut feel. A SWAG (Scientific Wild A.. Guess).
The newer truck automatically downshifts the 6 speed transmission when I apply the brakes long enough. So for long down grades I don't have to even think about manually down shifting. I think it does an excellent job of choosing the proper gear.
