***Free shipping for a limited time*** Plug-In Power In The Palm Of Your Hand

Works on all 1997-2004 Corvette C5's Including the Z06

Increasing horsepower and torque is as simple as pushing a button with Hypertech's Power Programmer III! 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!

When you connect the Power Programmer to your vehicle, its "smart" program instantly recognizes your vehicle's powertrain by reading the 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 lets you choose Hypertech's Power Tuning program for regular 87 octane or premium 93 octane gasoline. Both options improve performance without detonation. After the tuning program is selected, the Programmer automatically installs the program and allows you to access and reprogram the vehicle's computer to function properly with aftermarket components such as non-stock tire sizes and rear-end gear ratios.

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.
