That's 10% (6.2mph) either you have put very short tires on your ~Z~ or something else is going on....mine is near perfect with new rear tires (26.8,26.9") but as they wear down,you can get 1 to 1.5mph slower than readings of speedo....only 1-2%.
You may want to have something looked at/as i haven't heard of one being that far off.
