Thread: Difference in Speed reading on iGO and real gauge

Are you sure the real speed is 100, thus IGO is wrong?
Isn't it the other way around? I think it is, since speedometers in cars are legally (obliged by law) showing faster speeds than the real speed
Also tyre pressure is of influence, and the tyre size, and ...
