I have a 2015 Ford F350 Super Duty with 6" lift and 40x15.50r20 tires. My speedometer was not even close to being accurate. After installing the 730120 Speedometer Calibrator it is dead on. Hypertech's installation and programing instructions that come with the 730120 were very easy to follow and made the installation simple. Thanks Hypertech for a great product.
