Hi, itīs normal, that the speedometer shows 5 to 10% more speed, cause you are not allowed to be faster than the speeding limit defined by the law!!! - so you should be on the safe (=slower) side. Also little differences in the diameter of the tires must not cause too high speed. Thatīs why all speedometers show minimum 5% more! The SID computer shows the truth cause itīs more accurate for calculating distances. Check the speed using a stopwatch and the distance index on the motorway (1000m)! (30sek = 120kmph, 36sek= 100kmph, 45sek = 80kmph) (Justin - Iīm disappointed ...) Greetings -ROLAND- Charles Vaillancourt > Hello, > > I just bought a new 93.
