I have a premium 400A package. How/where do I find the rear gearing for my car? I am loading a tune and need this info??

Is it not on your window sticker?


As Travis said if you have 3.55's or 3.73's it will be on your window sticker. They were both a $395 option. If there isn't anything listed on your window sticker then your car has the 3.31 gears.

you should not need that info to load a tune, unless you are trying to change from the stock value.
