This calibrator doesn't work on my car.

I purchased a mustang with aftermarket rims and the speedometer is fast by 20MPH. After some research, I decided to purchase the Hypertech speedometer calibrator. I programmed it for the nearest Tire O available in the list. After the calibrator successfully programmed my vehicle, the speedo is still fast by 20MPH. I've tried programming every tire O and gear ratio option available, but my speedometer is still fast by 20MPH. I contacted Hypertech and they are still looking into it.
