to flash it you will need a programer like a flashpaq or hypertech or even the AEV and regearing isnt simple and you probabaly cant do it yourself unless you are REALLY good with taking your differentials apart so you will have to pay to have some one do it...to go to 5.13 i was quoted $1300 to regear

I sure hope you didn't buy your jeep expecting it to be eco-friendly!
