Hypertech speedometer calibrator

[Musky Mike]

Has anyone used a Hypertech speedometer calibrator on 2019 RAM? Did it work?

Yes I have one but I found a better way to change speedometer calibration .
AlfaOBD Software and kaobtech security bypass module/cable.
Plus you can change dozen of settings like have fog lights on with high beams. Do a search on this site for information.

Worked for me. Pretty easy to use too. Tip though, actually measure your tires, don't go off the tire mfr's datasheet for OD. FYI I have a 6" lift with 37" Nitto Ridge Grapplers, had the se setup on my 2013 F150 and had to deal with the speedo being off. This Ram speedo is pretty much dead-on after this correction.
