is there anyone out there who has added 4:56's to their 2012 6 speed? I have 4:10's in my 2012 manual rubicon now and wondering what the experience would be like if I went up one notch.

Would fuel consumption increase or decrease?
WOuld 1st gear become useless?

According to the charts it seems like id lose MPG's since I would be at a higher RPM at 70. Am I reading this right?

I dont hate the 4:10 gears at all its just that im coming out of a 2 door infinity sports car and am so not use to this lack of pep feeling.
