I think it may be a GDI dash issue or with how my car was put together, I had a number of problems when the car was delivered and being, for Morgan, a new dash setup the dealer didn't have any experience of it and no one at Morgan seemed to have much of an idea either.
Happy to confirm that the speedometer on my previous car, a 2004 4/4, was spot on so my comments aren't aimed at Morgans in general simply a problem I have with my car.
All my non Morgan cars have had speedometers that have over read because that's what they should do.
