Bully Dog Tuners came to be in 1998 as an enthusiast business focused on improving diesel engine performance in American Falls, Idaho. Since then, the brand has come to be known for its leading-edge engine ECU calibration, high-quality aftermarket parts, truck tuners and precision data-logging and 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 with Derive Systems, Bully Dog, Bully Dog Big Rig, SCT, and Derive Efficiency brands have integrated into a single world-class operation -- and a dominant force in the automotive technology space.
