Default 2010 Jeep JKU Sport Transfercase High and Low ratios

Hello fellow Jeepers! Recently I upgraded to 35inch tires and 4.88 gears and I was told that I need to recalibrate. So I decided to purchase Superchips Flashcal and recalibrate. On the other hand, my dumb*** decided to touch the transfer case high and low ratio and now I am not sure what the stock ratio is. I have uploaded a photo of the tag on my transfer case. All I need to know is what number to enter on my Superchip for "transfer case high" and "transfer case low".

Transfercase: NV241 Click image for larger version

Sorry for the up-side-down image. For some reason it does not flip around.

Hi is 1:1
Low is 2.72:1
That's what your tag says.

Sent from some string and a few tin cans.

So what I enter in the superchip. It only gives me the option to enter only one number. I can not enter in "1:1"

I don't have a superchips, but a good guess is '1' for high and 2.72 for low.
