Will gear swap affect speedometer?
Looking to change my gears from 3:73 to 4:10 on my 2012 F150 6.2. Will this affect my speedometer? Where is the speed sensor located? Can I fix this with the SCT X3? Should I change my shift points?

No, you should not change your shift points. Just correct the speedometer. Adjust it till the SCT's speed readout (not the speedometer) agrees with a GPS.
By the way, 3.73's to 4.10's are not worth the expense. 4.56's, that's worth it.
