Hey yall, me again

Just curious i got a 2.5" leveling kit and 33" tires, and now well needless to say my mileage is JUNK . Just curious im looking at re-gearing the rear end just curious what ratio would be best to go with. I mostly drive city but also a couple times a year do long highway drives and to get to the next town its 80km/h roads. Just curious what yall think.

Thanks again
