    Product Description

    Increasing horsepower and torque is as simple as pushing a button with Hypertech's Power Programmer III. You simply plug the Power Programmer into the underdash diagnostic plug, answer a series of "Yes/No" questions, and the Power Programmer does the rest. The Power Programmer is much more than a tuning chip - it is a self-contained automotive tuning computer.
