I have 2.5in level, 20 in XD Addicts and 35 in Toyo Open Country's. Around town I get about 13 mpg. I never really use the highway, but I recently took a trip to NC from middle GA and got 16+ mpg. And that was me and my wife, two kids and a bed full of luggage and ammunition. Did between 65-70 and had the A/C on.

With only 1000 miles on it I seem to be getting 16-16.5 hiway, 13 city, 8-9 towing heavy. Hope it gets a bit better but not counting on it. Only a 2" lift and 33's.

For anyone that's lifted, Are you running a tune? If so, what are you tuned for? I.E. 87 Performance/Tow, 93 P/T, or 93 P? I'm trying to figure out if im wasting money by putting 93 Octane in, or if I could drop to 87 or even 87 ethanol free and yield the same MPG numbers.

New 2014 EB; 3.55; 6inch lift on 35" tires.. 2600 miles... I'm getting 12.5 city and 14 HWY. Hoping to do better when I get some miles on the truck

How's your performance with those 35s? I have the 3.55 rears in mine also and Im thinking of running 35s but Im wondering how big of a hit Im going to take.

I'm sure it's not as peppy as my '11, with stock 18's, 3.73's, and a leveling kit, but it'll do everything I need to do. It just takes more pedal, and gas to do it.

The guy at Eastern Off Road assures me that when I get some miles and load an SCT tune, The Larger turbos on the 14 will make me very happy. I travel a lot of highway, at 80mph, so I like great gas mileage. That remains to be seen though. When I get my tuner updated to my '14 PCM, I'll make sure to get every tune with stock transmission tuning. All 6 tunes, for my '11, changed the tip in and shift pressure so much that I ran the truck for 4 years with no tune at all. It's not worth the aggravation of running race mode, hard shifting, every day of my life in a pickup truck. He tells me that with a CAI, and Borla, or Corsa exhaust his customers are getting 16.5 city and 18.5 hwy running my set up. Reason for the Borla or Corsa is because I told him I didn't want drone. Either of those, and an A.R.E intake will run close to $2K. I've only got 2,000 miles on the truck now, so it'll be a few months before I decide what to do. But.... We Do Love The truck

Not totally sure if it's relevant but I have a 2015 screw short bed. It has the 3.5 ecoboost, 3.55s with a 6 inch fabtech and 34.8x11.something wide. Just made a 5 hour trip each way last weekend and driving 75-80 the whole time I averaged 15.9 with 800 miles on it. Totally stock performance wise. I realize it's a little different but same motor more or less. Performance is still better than my 2010 5.4 scab with a level, 33s and on a 93 tune. Just my 2 cents. Hoping the mileage goes up some still once it breaks in and with a tune and exhaust eventually but I'm fairly happy so far. 14.7 lifetime millage this early on is better than I expected!

2013 running 6 inch fabtech on Toyo at 2 35x12.5x18. Averaging 12-13 right now. Best I've gotten in 16.6. Mad though cause it has 3.31 gears. Was told when I bought it (used from ford dealer) that they Vin searched it and it had 3.73. I tow 9500 lbs some times so I wanted 3.73. Oh well it tows it and never dropped below 10 mpg at 70 mph with that load. My stock 2011 eco fx4 with 3.73 averaged high teens in mixed driving and best I got was 22.8 at 75 mph
