I tuned my 2010 JK to the performance/regular fuel option, and I think I've noticed an increase in torque. Fuel economy, however, remains to be seen. My initial thoughts are that I'm getting fewer mpg's than I was getting stock, but I'll reevaluate after having used a few more tanks of fuel. The increased torque is nice, but if that's all, then I'm not sure this box is worth the money.
