Why use a tuner?
Whether you are looking for that extra bit of power for your tow rig, or simply trying to get better mileage, a tuner/programmer should be next on your list. A tuner communicates directly with your car/trucks computer via the OBD2 diagnostic port and allows you to take control of your ride. The many adjustable features such as speedometer correction, transmission shift point adjustment, diagnostics, speed limiter removal/set, and gauge monitoring, makes for the most robust tool at your disposal. The simplicity of installation takes away any doubt that you might have as to whether or not a programmer is right for you.
