Who We Are

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 with SCT under Derive Systems, Bully Dog has welcomed best in class technical and sales talent in addition to an extensive custom tuning and sales network.
