speedometer recalibration
I've changed the tires on my F250 4WD 2000 SuperDuty from
LT285R75-16's to LT325R80-16's. The Speedometer was accurate before and is about 15 percent off now. Ford said my tires are too big for them to recalibrate my speedometer. (they are 36.5inches in diameter and the limit is 35) I've heard about a device called Tru-Speed that changes this but several people have told me that it is not very accurate. (not to mention that it's almost $200!) I've got a western diesel chip installed so changing to something like a hypertech would be very expensive too. So anyone have any suggestions as to how I can recalibrate my speedometer? thanks, Robert If time is the 4th dimension, then money is the 5th dimension. We are always concerned about dollars per hour for the space we occupy. - Rod White |
