One speeding ticket can pay for the price of a speedometer calibrator. In minutes you can reprogram your speedometer so it will be as accurate as the day you purchased your vehicle. Installation takes seconds - just plug in to the easily available port next to your steering column. In minutes you can answer a couple of on screen questions and the speedometer calibrator does all the rest. Returning your vehicle to stock is easy too. Just re-connect the calibrator and follow the on-screen instructions and you are done. Will not void manufacturer warranty or affect normal operation. As an added benefit, many speedometer calibrators will also read and reset diagnostic trouble codes. That can save you hundreds of dollars in dealer charges and avoid costly and unnecessary service fees.
