Give etb a call, they're very approachable but off the top of my head, the tacho has dip switches on the back and may not be set correctly and the feed to the Speedo may be wrong rather than the guage?

Evening
I have had my car checked out, dynoed etc and it seems my rev counter is reading very high and my Speedo is reading too fast.
Are these things that can be calibrated whilst in position or do they need sending away ?

Thanks

James
