Where can I get one of these?

I just took mine into Ford and had them do it for $90. They also adjusted shift points as well as the speedometer

Ford can only do up to a 35" tire....

yeah thats the site for the speed wizard - and beleive it or not shift points are not even controlled by the abs module on most of these trucks, shifting is done via load and rpm. Except the 7.3L engines

but if you tap into the speed signal right after the abs module on the 7.3's then it will do the shift point change.
