Ive just joined the GTR register after just this week buying a very nice
R33 GTR.After 3 or 4 hours of driving,i am a bit dubious about how
accurate my speedo is.Anybody had problems with this before,or know how
to cure it?

How dubious?
Have you eliminated the obvious (like copnfirming whoever did the conversion from km to miles knew what they were doing :eek: ).

Are you sure the speedo is under reading and not the rev counter over reading? The latter is more common and makes you think the former is true.:)

How do you know it's under reading? GPS measurement? How much by?

We did mine last night, it has r34gtr wheels and nismo 320kph clocks.
The speedo showed 280kph and the road angel showed 170mph,
so it was only a little bit out.

Don't know about speedo but the uk speedo odometer runs about 10% fast, and when i asked middlehurst (who supplied it), they said it wasn't possible to recalibrate.
