2015 Toyota Tundra 5.7L
Awesome product!!! Great step by step instructions. Had 0 problems with the installation, it took about 45 minutes from start to finish. I would recommend you measure your tire to get the exact size. I upgraded to a 22in wheel with 35s and programmed 35s first and it was still off 2 MPH. Once I measured and saw that it was really a 34, I programmed that in and it was perfect. Much smoother shifting too. I also noticed a 2mpg gain too!!! This is a must if you have a lift Tundra with 35s or larger
Worked at advertised
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.
