    Need help with gear/tire wizard on 4.0.12

    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

    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"
