It's a well-known fact that no speedometer can be 100 percent accurate. But as long as your vehicle is maintained at its factory specs, the speedometer can register the speed within the permissible tolerance range. In case your vehicle is modified, its speedometer need to be recalibrated. The most common thing car owners do that affects speedometer accuracy is changing the tire size. This is because larger tires cover more ground in one complete revolution.

    Great Tuner!
    After hooking up 4 times and updating 4 time ,I eas finally able to program mu truck, a 2017 Silverado, was able to turn off the AFM, set new tire size and program to get better fuel mileage, the 1st 2 day it wouldn't read, say that unit would truck, but after talking with tech support by the 3rd day I was able to read truck. You have to update, hook to truck and update 3 times, when first reading truck is gets truck ID, then update to get the program for truck, "I completely satisfied with my purchase".
