We have invested in people, not machinery. The knowledge and skill of the Hypertech team are our most valuable assets. Our staff of engineers and technicians has degrees in a variety of disciplines, including electrical engineering, computer science, and mechanical engineering. Hypertech people know computers from the inside out! The Hypertech team is passionate about performance. We have racers, hot rodders, and performance enthusiasts on our staff. You'll find modified trucks and street machines in our employee parking lot. We build project cars and use our trucks for towing on weekends. We come from different backgrounds, but we have all learned to appreciate the tremendous power of electronic engine controls to improve performance on the street as well as on the race track. Hypertech is the technology leader in High-performance engine tuning computer-controlled vehicles. Electronic engine controls have evolved rapidly since their introduction in the early '80s. Hypertech has kept pace with these rapid advances in technology by developing power tuning products that take advantage of the capabilities of these electronic controls. Early automotive computers used replaceable PROMs or chips to calibrate the Electronic Control Module (ECM) for a specific engine, powertrain, and vehicle combination. Hypertech created the original Power Chips to recalibrate these electronic brains for improved performance. As the power of digital systems expands, Hypertech will continue to design and manufacture power tuning products that are on the cutting edge of technology.
