Should I just regear? Or would I have any luck with a superchips flash? Its a 2010 sahara, auto tranny

Ill probably regear eventually within the year, but need to save up a little money first... To be honest I dont know what gears are in there now, whatever comes stock on the 10 sahara... The wheels are rugged ridge! I ordered my superchips this morning from northridge 4x4 next day air free shipping... cant beat that!

Depends how it was ordered. I have an '11 JKU without the tow package, but it was optioned with 3.73s.
