33s now what
ok i have a 2012 auto sport 4 door as of now we just do mild off roading. i just put 33s on it and the performance has drop i knew it was going to do this and id lose mpg but whats the follow up mod for this gearing and a chip/re programer but what gears do i need and for what. ive been told as high as 4.56 and to just run the 3.21 that it has. i was thinking 3.73 would work best for the gas and the off roading but im new to this . do i reprogram first or gear

Im not sure upgrading to 3.73 is worth your money. I would run 3.21 for now until you one day upgrade to 35's. However, if you don't go to 35 EVER, then I would go to 4.10. You might as well just find a Rubi transfer case

is it safe to assume that you did NOT recalibrate your speedo yet? if not, you really should do that first before spending any more money than you need. sure, you will need to get something like an aev procal to do it but really, that's chump change compared to regearing. with your speedo calibrated, your computer will have more accurate shift points and, i think you'll find that your power loss isn't as bad as you think.

The only thing stoping me from
Recalibrating the jeep is that it's a 2012 with the pintastar I'd hate to go in for the head and they decide that it was my fault the head (that thousands of people have issues with) messed up

LOL!! Could you PLEASE use some punctuation when you type? I know it's the in thing to do today, but it totally sucks to try and make head or tails about what you're saying without it.
