recalibrating speedometer on a new GT
I just bought a new '06 GT with Auto tranny and the dealer is installing new 20" wheels on Monday. When I asked them whether they would recalibrate the speedometer, they said that it wasn't necessary!? I would think it should be done? Can you provide some help on that? :(

I think that would only matter if the car was under lease, even then the dealership would only go by whats on the odometer at turn-in date. With the new Mustangs I can't see a bigger wheel making that much of a difference in mileage, although it could.

Re: recalibrating speedometer on a new GT
Depends on the overall height of the tire. Are the 20" a bigger overall diameter? There is a certain amount of N/V that the computer will learn. Your other option if the dealer won't do it is to get a handheld tuner like the SCT Xcal2 and adjust it via the tune.

Someone put Carol shelby 20'S on at my dealer and it did need the recal. And yes they can do it at a dealer.I would go to a different ford dealer!Tuners are good for mods to rear gears firmer auto shifts.Adjusting fan temp turn temp.and more power!
I have a superchips tuner.It works great. |
