I tried to to adjust a A4 C5 Corvette for a new 3.42 gear from a 2.73. The original tire/gear ratio in the wizard was 9.51. I was assuming we divide the tire size by the gear? I came up with 7.8 (26.7/3.42) and the speedo is way off.
Everything I google has videos for older versions that looks way easier to use. ON this 4.0.12 version I'm running we only get one box to enter a value.
HELP please.
Thanks
