many threads on this, but Hypertech speedo calibrator is the only solution for 37"s. You can use Forscan for 35's and under

You can get close to a 37 using ForScan, I think KubotaOrange76 has figured this out...anything more than that and a product like the one suggested above is your best bet. I run 37's and have left mine, if anything I like "less miles on the truck".

I used Forscan to correct the speedometer, but it illuminated a CEL. I don't think there is any way around this. I got tired of the light and installed the Hypertech speedometer calibration module. Install was very easy and speedometer is accurate.
