Maybe I am the last to know but I found an app for those using a smart phone to check the speedometer reading verses how fast you are really going. The app is called DIGIHUD. down load it to your smart phone take a drive and see how close or far away your speedometer is. Mine turned out to be about 3 mph off. now i am not sure if it's worth fixing or how to.

Speed changes with tire size and the speedometer gear inside your transmission.

I use GPS on my laptop to check speed. You can also use mile markers to check your odometer. Go ten miles on any interstate and see how far off your odometer is. The speed will take care of itself. - Dave
