Default Speedometer Programming in '02 XLT
Did a gear change in my '02 XLT to 4:11 for better pulling. Does an AWESOME job pulling my 25ft trailer (hardly know it's there). Problem is speedometer is off and Ford reprograming will only take the program to a 3:75 ratio. Looking for ANY suggestion to get the speedometer calibrated correctly.


Looking for ANY suggestions.

A tuner / programmer can correct for that easily.

Default 04 Heritage with 4.10
Did the same... put in 4.10s and the dealer says they can't calibrate my 04 f150. It is just a computer, any variable should be able to be set.

Most aftermarket programmers can correct that for you. Check out superchip or any of them really.
