How are you calculating this MPG? I have 35" tires on a similar stock vehicle, and i'm just barely hitting 10.9 MPG. My factory lie o meter has been recalibrate, but it's still off by several revolutions, so with your 37" tires, you can't be calculating this number by looking at either your odometer, or the lie o meter.
I made my calculations by using a GPS to calculate total mileage for an etire tank, since my odometer / speedometer / lie o meter are all off now.
Just curious because I've heard lots of folks with DPF and tuners getting much better mileage than I am, but you are the first who is running a stock vehicle and claiming better mileage with even larger tires. What gears do you have installed??
