So like the title said, I get some terrible gas mileage. I have an o/r x pipe and the version of the diablosport predator before they removed the option for you to turn off the rear O2's. I followed all the instructions on the manual to have the O2's turned off and have the "Predator Tune" loaded in my car. I first thought it was because of my right foot, but I drove the car lightly on a tank and still only went 160 miles before I was on empty 
What's going on here?
It's warm and humid in Miami so I have the A/C on most of the time, and we have a bit of traffic. I also have 4.10's, but do no highway driving. The Predator Tune just says "Use premium fuel" and I put 93 into it.
Could my front O2's be bad? It's not throwing a code...
