Speedometer Calibration

[Hornet4096]

I just purchased a ‘24 1500 w/5.7. It has a 6” lift and 35’s. I need to calibrate the speedometer to the 35’s. Can anyone recommend a tuner that will allow me to do so?

Tazer. Did my speedo with bigger tires in a few minutes. Doesn’t get any easier than that.
Lot’s of other options to use it for as well.

Does the Tazer need to stay plugged in for changes to stay?
