I was running lean. The shop hooked it up and checked the fuel trim/curve. The truck was adding 7% to compensate for running lean. The whole reason I got the intake was to improve my mileage and it looks like it just hurt it. I took the intake off and it doesn't misfire anymore. Just installed the Edge. My truck is now completely factory except for the edge and it runs good. Have only run the tow setting thus far and like the shifting/throttle response. Not a huge difference but it is noticeable. Not like a diesel though...obviously
