So I know that the corvette gear ratios are 2.73, 3.15, and 3.42 for stick cars........Why do I see 3.42s for every file I see in the HP tuners repository even though they claim its a stock c5 automatic? This is confusing me. Even my own car which is a 3.15 when I read the file and was showing a 3.42. I went in and changed it to 3.15 and it stuck. So what is the deal here??
