Need to get my speedometer corrected for 37.5" tires and will gladly pay someone for their time. Tried at the Ford dealership but no luck. Can anyone help me?
Thanks.
Hello guys,
Purchased a 2000 F350 and it has 10 lug Alcoa 22.50's with 275/75/22.50 tires. The speedometer is off by approximately 21%. I went to a local Ford dealer and they tried to flash the ABS module with the correct revolutions per mile but the speedometer disprepency never changed...
