I used 93 octane performance tune for about a month and I noticed a difference in the power especially when off road.
As for fuel, there wasn't much difference that I could see, but then again I was running 35x12.5x15 tires so that probably didn't help any. I ran the 87 octane tune for that.
The main reason I wanted the programmer was to I could change my tire size to reconfig my spedo for those tires.
Now I have to try and figure out how to un-sync it from my Jeep so I can sell it.
