I have almost the same setup. stock 4:10 rubicon, 2 door and the stock 32 BFG M/Ts, 6-speed and 3.8L. Almost all of my driving is in town, constant stop and go traffic and I get the same mileage. 14.5-15.5mpg WITH my Superchip Flashpag.
On the highway it is much better. I get 18-19mpg on the highway with my Superchip Flashpag.
I use the 89 octane tune with my Flashpag and run 89 octane fuel. I've tried all the different settings and the 89 octane tune gives me the best performance to MPG ratio.
What the Flashpag does best is improve throttle response and low end torque. My throttle response is much better with the Flashpaq and my low end torque is a little better. Keep in mind I have a 6-speed and 3.8L. With the automatic I hear the shift programming makes a big difference with the 3.8L.
Given that you have the 3.6L your experience with the Flashpaq is anyone's guess... That's if it is ever released for the 3.6L.
