What RPM range should I be shifting?
Yep, as everyone else has said, above 2500RPM. The Jk's 3.8L V6 doesn't really start to make power & torque untill well after 2000RPM so short-shifting will result in you taking longer to pick up speed and use more gas as a result.

I'm pretty much the same as everyone. Around town its around 2300 at the earliest. Getting on the interstate I let it push 3500. I can't figure out a cruising rpm though. 5th gives me about 2600 and 6th gives me around 2000 or a touch over at 65-70. I usually let it cruise in 5th with 3.21s and stock 32s so around 2500 plus or minus 200. Anybody do anything different?
