Speedometer Forscan Fix for 37 Inch Tires

[26PlatinumPLUSAG]

I'm not messing with it either for a 2 mph delta at 70 mph with 37's

That's about where I am at.

my stock truck speedo with the 285/75-18s reads fast by 1-2 mph. i am guessing with 37s, it will read just slightly slow.
i'll probably just leave it and get some of my accelerated warranty loss back
