Who We Are

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 Big Rig, Bully Dog, SCT, and Derive Efficiency brands have integrated into a world-class operation and a dominant force in the automotive technology space.

What We Do

In 2006, Bully Dog launched their first aftermarket product for heavy duty semi-trucks/articulated trucks. More than just raw horsepower, Bully Dog’s goal from the beginning in the heavy duty market was to calibrate engines to run more efficiently, and in turn produce measurable improvements in fuel economy. With intimate knowledge of the heavy duty lifestyle, Bully Dog understands just how essential mitigating rising fuel costs is to each and every operator’s livelihood. Bully Dog’s passion for excellence is making Bully Dog Big Rig–now a full-fledged heavy duty outfitter–a market leader in the heavy duty market. With wide variety of turbochargers, intake & exhaust manifolds, accessories, and the industry’s most highly-advanced tuners, big rig owners across the globe can become better equipped to maximize performance and efficiency on the route ahead.
