The Unichip Plug n'Play Performance Computer Module adds the power you thought should have come from the factory! Tested for over a decade, the Unichip is designed to take full advantage of the hidden power in your engine, and only takes minutes to install. The Unichip is a multi-processor computer-designed to talk with your engine and program it for maximum performance. A custom-designed harness made specifically for your vehicle makes this possible, connecting inline with the existing factory connectors. These Unichip Performance Computer Modules will work with Stock or Modified engines with aftermarket Air Intake systems, Cat-Back Exhaust systems and all headers.
