Calibrating New Speedometer

 Getting your speedometer calibrated correctly after switching tires is super important for staying safe and avoiding speeding tickets. When I changed the wheel setup on my truck last year, I used a Mileage Blocker from Dynotest https://dynotestpro.com/ to protect my odometer during the long calibration drives. The great thing about this specific device is that it allows your speedometer needle to function perfectly normally while it keeps the odometer from moving. This allowed me to compare my dashboard speed with my handheld GPS unit accurately without adding fifty miles of testing to the vehicle. It is very easy to use and didn't cause any single error message. It will definitely make your calibration process much cleaner!
