I use 87 Performance and I also bought the transmission app through their web updater. So now I run a custom shift schedule and have customized my torque management as well.

What are you getting for fuel mileage?

My average is 12-13mpg for city/hwy driving.

Before I messed with the shift schedule, I was getting a solid 13 mpg on average between city/hwy. However, I really enjoy the response of the jeep with the new shift schedule - especially where I live since there are a lot of state highways with traffic lights, so its common to go 60-65mph. Stop at red light. Then climb back up to 60-65mph.

What's are people getting for mileage with 91 octane tune I heard it's night and day difference for power between that and the 87 octane tune

I have a 3875. Complete garbage on mine. Tried running the 87 tune and it made it a couple hundred miles and started pinging. I ran the mileage tune for a bit but not long enough to determine any MPG gains. My tuner has said "cannot detect key on" and lost communication with the ECM multiple times and basically froze itself up. The first time it did that, a couple days later my FDCM wigged out, caused major problems, and had to be completely replaced...coincidence, I don't know. After this last time the Jeep threw 11 codes. I bought the trans app and their system didn't recognize it, a tech had to force it onto my tuner. The only thing mine is good for is tire size changes and clearing 4WD codes. Needless to say I have no trust at all in SC and run mine stock.

I have had good results with my flashpaq. I traveled from TX to NE and back for the holiday weekend, and I got 18-19mpg on the interstate and 20 mpg's when going 65 on smaller highways. I run the 91 performance tune and have it tuned properly for my tires. I have skinny BFG'S on it that measure out to just a hair under 33", and an OME MD lift. Around town I usually get around 14.
