VY SS - S1 - 6 Speed Manual
Recently bought my first commodore (VZ SS) and the first thing that I noticed was the speedo is reading about 80% of the real time speed. The car is on newish wheels and recently had its diff replaced (not sure what ratio, was done by previous owner), so no doubt that would explain for the inaccuracy.

I'm new to commodores but when I was fiddling around with the dash cluster options I saw a calibration option. Will recalibrating this feature fix the speedo issue? Or is it something I'm gonna have to take somewhere to get fixed..

Any help appreciated :)

You need a diagnostic tool to change it, cant be done yourself. Holden can do it aswell as most performance shops around perth.
