speedo going faster than me

[dj g]

yeah GPS is the best way. mine was within 1mph of the GPS speed all the way up to 120mph and I'm running wheels 3inches bigger than standard!

if you've changed the box you could have the wrong bit in the there reading the speed. I know there's a white and red one in the 140 and 160mph 'boxes for the mk2. maybe that has something to do with it.

is it a constant 10mph out throughout the range or varies? has someone changed your dials to white ones and stuck the needle on in the wrong place. I know mine rests at 10mph and then doesn't move until I get to 11mph.

thank you dizzie not trying to seem thick but what do you mean by gps

global positioning system, it uses statalites to position where you are an speed is worked out as a function of distance traveled over time

God mine has that problem to the speedo is about 15 - 20mph faster than what Im doing  however the
Mileometer works spot on !! Could it be the clock that is at fault !
