I recently put bigger tires and lifted my F150. When i did that the speedometer and navigation was off. After a bit of research i was lead to this speedometer calibrator. Once i received it, it was easy to use. Just follow the prompts. Within about 5 minutes it was done and my speedometer was dead on and also fixed the issue with the navigation being off( Nav runs off of speedometer and GPS signal) I would definitely recommend this item.
