Here's 315/70/17... basically 34.4" they are raptor rims so offset is 34 vs 44 offset ...2" level front only

Am I missing something? I have looked all over there site. I see nothing about calibrating the speedmeter for tire size.

they use n gauge for a tuner.. all I could find on 5 star site is on the order form to enter tire size

On stage 3s website and that tuner they reference tire size

It's late and can't find the user manual for the tuner, but for the mustang and older 150s they reference selecting tire size

They are the only tuner/calibrator that I have seen for the moment for our 2017. Hypertech has an inline speedometer calibrator, but I still do not understand the true difference from this one to the regular plug and play device. Not sure exactly what it does differently as well as not wanting to take out part of dash to get to guage cluster. Hoping they will get one soon.

superchips just released their flashcal tuner that calibrates tire size for the new 2017 3.5 eco.

Thanks for the information.. I know it wants tire size, and axle ratio but I believe that is for the actual tune so it is right for the truck. It does not indicate it calibrates the speedometer that I can find.

diablo sport predator 2 has tire/speedometer calibration.
