Anyone who has installed 37s, have you recalibrated the speedometer? If so, what device did you use?

Hi,

Just picked up my RHO this weekend. For folks who have installed 37s, did you recalibrate the speedometer? If so, what device did you use to recalibrate?
I'm thinking of putting 37s on the stock wheels (no lift for now).

Thanks

I did not recalibrate as i never drive the speed limit.

I will eventually if Tazer or AlphaOBD figures out the canbus system on this truck
