    Tuner Changed Gearing In Speedo Menu

    Just got my car back from the transmission being rebuilt and I noticed the car shifting soft and slow. They re-flashed the TCM, so I was going to re-write the tune that I had saved so that it would be shifting right again and I just happened to notice that the Final Drive settings were changed. My car has 2.92 gearing, which is what it says under "Ratio", but under "Trans" it says 3.27. Should I change this back to 2.92? I'm assuming they just grabbed a base tune from someone else's car and forgot to change the ratio.
