What is the Axle Code or Gear Ratio on the 05 GT? Need it for my X-Cal2 Custom Tune from BamaChips?

 

open your driver door..you will see 2 white stickers..it's on the bottom of one of them..it says axle and below it it should be 2 letters or numbers..mine I think was CG. hope this helps. you won't be dissapointed in doug's 93TQ tune.

 

Manual - 3.55
Automatic - 3.31

 

The ratio is also printed on the sticker on the back of the diff: Don't peel it off if you paint!
