Diesel Pros » Bully Dog

Bully Dog began in American Falls, Idaho in 1998 as an enthusiast business focused on improving diesel engine performance. Since then, the brand has come to stand for leading-edge engine ECU calibration, high-quality aftermarket parts, and precision data-logging & monitoring technology. 

Bully Dog is at the forefront of performance ECU calibration technology for gas and diesel vehicles looking to add performance, tackle tough terrain, haul heavy payloads or tow trailers over long distances. Their calibration software platform adjusts key performance parameters to better respond to the unique demands you put on your vehicle, whether it's adjusting for tire size, axle lockers, throttle sensitivity or shift firmness. Easy installation using one of their advanced handheld programmers means quick, out-of-the-box access to better performance, added safety and improved fuel economy. Bully Dog also offers a precision-engineered, top-quality line of performance intakes, diesel particulate filters, manifolds and turbochargers to help vehicles run stronger and last longer.
