hey all,
recently had my zf box built with new convertor, exedy stage 1 friction kit, bronze bush kit, oversize pressure regulator, new steels and a new clutch e pressure plate etc.
I've noticed my speedo is now reading out, at 40kmh it reads 50 and getting up to 100 it reads 80 on the speedo. the zf has previously had a tune and im thinking will it need a retune on the box to sort my speedo out or have I got other problems?
I've already tried returning the tune to stock on xcal 3 and reloading the tune in hope it might fix the problem but no good.
any help appreciated thanks
