their are few rocks to crawl in memphis, but there is hypertech. just installed the tunning on my 08 jk, works great. i am one of the bata testers (lucky me). my jk has a 3" full traction lift with 35" xtreme m/t's, a 6 speed,and 3.73 gears. the added torque has really helped with the sluggish feel when taking off and at highway speeds 6th gear is now completely useable. will give update as time goes along.
