Just a quick update....
I had the tires installed and they made a world of difference in the looks of the Expedition. I love it.
I called 3 different dealers in my area and they all told me that there is no way to change the calibration. And the 2 offroad shops around me want to sell me a $300 adjustable "box". Im throwing the BS flag on this one. I guess I will live with it for now until I buy a programmer.
you can always get a cheap GPS and watch the speed on that... until you get a programmer
I plan on installing a pc in the Expedition with a gps as soon as I finish up a couple other small projects. I just need to find the right touch screen, remold my bezel and relocate the climate contols.
Thanks for all the replies and information.
I have 275/60R20 on my 2014 expy and i think i notice a different in the way it shifts. Especially on the highway trying to pass. Seems to be in too high a gear. My stock size was 255/60R20. I am also deciding which tuner to get. The dealer says they might be able to program it for $120 but it's not guaranteed to work.
