Speedometer Calibration

Your vehicle’s speedometer measures the number of driveshaft revolutions per mile, which is displayed on your dash as speed in miles per hour. When you make certain changes to your vehicle, you change the ratio between the numbers of driveshaft revolutions per mile. The speedometer must be calibrated to accurately reflect these changes. Advanced Automotive Inc. can help. We offer fast, friendly speedometer calibration in Chantilly, VA.
Most vehicles on the road have speedometers that are reading 1-3 mph off. Even brand new cars and luxury cars can have inaccurate speedometers. Changing gear ratio or tire size can lead to an inaccurate speedometer. Driving around with an incorrect speedometer can be dangerous and could earn you a speeding ticket.
