Did you by chance already do the "2-Mile Calibration" procedure?

...Onto the calibration procedure itself, the easy part. Current Auto Meter Speedometers use the Trip Reset Button as the calibration button, some earlier Auto Meter Speedometers use a separate calibration button. We include a pushbutton that is used for the calibration steps on models which require the separate button. Once you have everything installed and before you start the motor, follow these steps


1. Press and hold the button while starting the vehicle. Once the motor is running, you can then release the button after the pointer goes to the highest MPH reading and stays.


2. Drive to the beginning of your carefully measured 2-mile distance, and stop. Press the button again, and the pointer should then go to half of the maximum MPH reading, and the speedo is then ready to be calibrated.


3. Drive the two miles, stop, and push the button, the pointer will drop to zero and the calibration is complete and the speedo should begin indicating the speed when you start driving.


On models that use a separate calibration button, you may either keep the button wired in or remove it.
