I switched from the stock silver face instrument dash to an OEM dark face one. The replacment tach shows 500-600 RPM while the old one showed 1000. So I don't know if the original or the replacement OEM tach is correct.
Does anyone use another temporary tach for tuning?
Also, is there a way to calibrate the factory unit against the external one?
