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. With a talented and well-rounded team of designers, engineers, quality control professionals, salespeople, and customer support staff, Bully Dog continues to produce innovative technologies that make use of advances in mobile computing, Wi-Fi & Bluetooth communication, cloud computing, and performance monitoring to deliver unparalleled performance. As a result of its recent merger under Derive Systems, Bully Dog, Bully Dog Big Rig, SCT, and Derive Efficiency brands have integrated into a world-class operation and a dominant force in the automotive technology space. 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. Our 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 our 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.
