00 4Runner Speedometer

I just purchased a 00 SR5 4WD 4runner. I have a handheld GPS that will give a speed reading. It seems that the speedometer in the truck is about 3 mph too fast. The tires are factory size (265 70R16). Is there any way to calibrate the speedometer? The odometer seems to be reading correctly.

Thanks, Bill

3 mph u r joking right? there is no adjustment that can be made :nono:
