Anyone have experience with the Bully Dog add-on for diesel engine? Information suggests 10% increase in mileage and 15% bump in HP.

I have triple dog and only run tow/economy mode. I get 24mpg around town and 12.5 towing (hand calculated). I am light on the gas and have a 2wd 6 speed so that helps. I was having issues setting tire size for my new wheels and uninstalled the tune for a bit. The difference in power and economy was noticeable (mpg towing dropped to 10).
