Power Module Chip
The Power Module contains a dyno-tuned Power Chip mounted on a circuit board that easily plugs into the Ford computer's service port. The Power Module delivers more horsepower and torque, faster acceleration, and improved throttle response. Depending on application, the Power Module also controls the cooling fan "on/off" temperatures, permitting the use of a low-temp thermostat for a cooler, denser intake charge. It also raises the top-speed limiter to compensate for the speed rating of factory-approved high-performance tires and firms full-throttle transmission shifts for faster acceleration.

Power Chips
Early automotive computers used replaceable PROMs or "chips" to calibrate the Electronic Control Module (ECM) for specific engine, powetrain, and vehicle combinations. Hypertech created the original Power Chips to recalibrate these electronic "brains" for improved performance.

As interest in Power Tuning grew and the variety of OEM systems increased, Hypertech developed innovative products to complement the increasingly complex on-board computer systems. Our engineers designed special carriers and mounts that allowed Hypertech Power Tuning programs to interface with the computer in a wide variety of vehicles.

In 1994, calibration chips were eliminated and the new generation of Electronic Control units (ECU) utilized programmable memory. Hypertech created the Power Programmer to upload Power Tuning programs directly into the ECU. Today Hypertech Power Tuning products span the spectrum of automotive technology. We continue to offer our famous Power Chips for older vehicles, while constantly updating our Max Energy and E-CON Power Programmers for the latest cars and trucks on the market.

Hypertech Power Chips are direct replacements for the stock chips in 1981-1995 GM vehicles. The Power Chip contains the Hypertech Power Tuning data that controls the engine's air/fuel ratio and spark advance for maximum power and performance plus, potential gas mileage improvements. Power Chips can be installed easily, using only hand tools.
