Huge increase in performance. No turbo lag and the diesel runs smooth. The different settings allow for programs for towing, fuel economy and performance. The performance setting has increased fuel economy.... As long as I keep my foot from stomping the gas pedal. Increase from 11 mph around town to 14 mph. Not tested on the interstate yet.
