Speedometer calibration
Have a 2014 wrangler unlimited went from stock tires to 35's. Is there any way to calibrate the speedometer? It is about 4-6 mph off depending on the speed.

got to have a programmer... if you think its off my 4-6mph...it probably MORE than that... get the Superchips FLASHPAQ or the Trail dash.... it will allow you to tune, change tire size, gears tpms, just to name a few things it will do...
I got 35's about 2 weeks ago and with out the tuner it would SUCK to drive...

Programmers - are cheap and have a lot of functions in addition to recalibrating for tire size. - $150-ish (AEV ProCal, Superchips FlashCal)
Tuners - are more expensive, but allow you to add various performance tunes as well, for a small increase in hp/torque. - $300+ (Superchips Flashpaq, DiabloSport InTune, Hypertech, Bullydog, etc)
And then there are the fancy, expensive tuners with nice displays - Up towards $600 (Superchips Traildash, DiabloSport Trinity, etc)
Any of them will calibrate for the tires, you just need to look at them all and decide which extra functions/options you want. There have also been a few hiccups with certain tuners and certain newer years of JK's, so be sure and do some searching on whichever one you like.
