WHO WE ARE

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