The JET Performance Programmer lets you take control and program your own vehicle computer to match your driving style. JET?s exclusive Tri-Power tuning allows you to program for performance using lower cost regular octane fuel, or for optimal performance gains you can program for midgrade or premium fuels. All three tuning modes are designed to operate the engine at peak efficiency based on the octane level being used to improve horsepower and mileage. The advanced technology and design of the JET Programmer gives you the ability to modify air and fuel ratios, ignition timing, shift points, shift firmness, speed limiter and rev limiter settings. The programmer will also correct your speedometer and turn off the ABS system trouble light if you change tire size or gear ratios. Also includes a built in scan tool to read and clear diagnostic trouble codes when your check engine light comes on saving you a costly trip to the dealer. The programmer simply plugs into the vehicle's diagnostic port under the dash and then the easy to use installation software allows you to make your changes by answering simple yes or no questions.
