the Raptors nav should be disconnected from the wheel speed sensor so when we run larger tires the nav doesn't go all crazy and put you in a field on the other side of the road.
I don't think tires size would affect placement of your truck on the Nav, it's based on GPS.
I'm assuming your running a Tune, yes?
Otherwise the time to arrival to destination will be off.
Speedometer will be off too. Not to mention shift points.
