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.
