Bully Dog for Cummins 400 HP
Anyone have experience with the Bully Dog add-on for diesel engine? Information suggests 10% increase in mileage and 15% bump in HP.

I've used other brands. You'll see more power, but I've never seen any better fuel consumption that I could measure. Makes driving more fun with the extra HP, but that might even cause you fuel milage to decrease because you could have your foot in it more......
