Ford Mustang GT 46L 02 04 Power Programmer III

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 YesNo questions, and the Power Programmer does the rest. Depending on the application, atleast 8 to 10% power gain can be seen. On some applications a dramatic improvement of up to 18% has been reported. When you connect the Power Programmer to your vehicle, its smart program instantly recognized your vehicle's powertrain by reading its Vehicle Identification Number VIN. The VIN contains specific information on the engine, transmission, and drivetrain, which the Power Programmer decodes before it downloads the Power Tuning program that is precisely tailored to your car or truck. The Power Programmer is incredibly powerful, but it is also incredibly easy to use. Reprogramming does not require any tools or knowledge of cars or even computers plus you can return to OEM stock programming in just minutes.
