3.73's in an auto are about equivalent to 4.11's in a manual. I wouldn't go 4.11 in an auto personally because you run out of gear too quick and if its ever a DD your gas mileage will go to ****. Not to mention on the highway gets very old with an auto and 4.11's...

I personally love how my Motive 3.73's and Yank SS3600 drive on the interstate. At 70mph with cruise on I'm crusing ~2500rpm.. Haven't noticed too bad a drop on gas mileage yet but 4.10's is too short IMO
