The reliability issue is maybe just speculation at this point, but loss of mpg is real. To me it makes no sense at all to buy premium fuel and then lose 2-3 mpg on top of it. That's likely extra $100 out of the pocket each month. For that money (given monthly payments) I could get a real performance upgrade, like a turbocharger. Sure, it will still need premium fuel, but at least it won't hurt the mpg, and will give undeniable power.

If this is really not what you said, then whatever is that you said made zero sense.

This morning I filled up with 92, swapped to the 91 tune and noticed a nice increase in throttle response. Maintaining 80mpg on the interstate wasn't as much of a struggle. as well during my ride there was a yellow light that normally I would have to stop for or down shift to make it through and I felt comfortable enough to stay in 4th, accelerate a bit and make it through safely. All in all I'm happy with it. 87 noticed zilch, but the 91 is a nice improvement over stock IMO.

So long as you have realistic expectations from the power gains of a superchip, you'll be very happy with it and notice at least more sensitive throttle and some mild increase in low-mid torque. My JK is a stick and even I know I feel a nice improvement in power. Haven't noticed any + or - in mpg's. I normally run 87 tune on 89 fuel, haven't really played with 'tow' or 'crawl' modes yet.
