    I have a 2014 Tundra TRD Double Cab. 3" lift, leveling kit, 33" tires, and a camper shell. Just bought it and the MPG are killing me. I am wanting to free up some horsepower. I am looking at Bulldog units, intakes, and anything that is a good starter. The power if great just want the MPG to increase some. I am currently getting about 15 city and 13 hwy. Yes I know that seems backwards but thats what going on.

    Welcome! That is odd on the MPGs. Do you go over 80 on the hwy?
    You only have 33s but might look at the hypertec speedo calibrator.

    I get ~14.5-15 Hwy if i stay under 80. If over 80 i get 11ish.
    Mixed ~13-14
    City ~11.2-12.8

    If you want better MPGs one of the first things I'd do is put less aggressive tires on it. Those MTs are heavy and very inefficient.
    An intake wont net any MPG increase, an exhaust maybe very little (.5 mpg). I've heard the hypertech tuner and similar could net a slight increase but I've never tried one.
    Biggest killer of your MPGs is the lift. You can fit 33's without the lift, maybe remove the lift if you're concerned with the highway MPGs. Basically the truck is a brick moving through the wind at highway speed, make it taller and now you're just pushing even more air. I lost 3-4mpg highway with my lift and mud terrains.

    That's pretty much right on compared to what I get for highway. . My city #'s stay fairly steady at 10.9 to 11.1
    15 is real good for city driving. You should be getting that for highway mpg at reasonable speeds to 75 or so. Not sure what to make of it. Welcome by the way from CO.

    I normally set it at 75. I drive about 35 miles to work one way. I know it seems backward but I am wondering it the camper shell is just creating that much drag at higher speeds. I have a daily gas getter so I'm not to concerned and definitely don't want to take the lift off the beast. Lol.

    If with stock Tundra, mpg will not be impressive at 75 mph. The optimum speed for mpg is around 55 and drops off rather quickly.

    As others have mentioned, the biggest factor (besides your right foot) is the lift and the heavy tires.

    A light foot!! Haha
    I've done a lot of reading on the same thing. Here's a few things I've found...CAI are not worth it.
    The truck already has one. Put in a nice drop in filter and also Google "SABM" (Stock Air Box Mod). For the price I think it's a great addition for a little gain. Maybe the Bullydog programmers also like you said. Have read some good things about that. And also look up BAMufflers. They were made for Tundras and a lot of people have claimed a boost in HP and MPG. That's next on my list. Just a few ideas for ya to look at and think about.


    Nice looking truck by that way!

    I get get my my best mpg @75mph on cruise. Actually sucks at 55mph. At 55mph I'm lucky to be in the 13's. Usually mid 12's at 55.

    My truck likes around 65mph cruising, down around 55-60 it kind of lugs 6th it feels like, get up around 10mph more and its more in the power band it feels

    I agree. It seems the best band is the 65 to 75 range when cruising and temperature.

    Not to be blunt...but why purchase a full size truck and expect great MPG's? I never purchased a truck with the expectation of what its rated at or, planned on better.

    I can't understand why I'm not getting 25 mpg. I dropped in a K&N.........

    I agree with everyone. I never thought I would ever get good gas mileage. But heck...if we can go buy or do a few mods to MAYBE help us get just a little more juice out of our engine then why not. It's a win-win.
    .....And it's just plain fun to buy stuff for our trucks.

    I know I have gained maybe 1.5 mpg tops with, tonno, K&N, and Borla muffler combo. May not be much but I'll take it.

    Gotta admit. When I bought mine, for the first 2000 miles or so it seemed I was filling it up every other day. Guess it was the break in period or something. Also one thing to remember, these fuel gauges are as little weird. When it says 1/4 of a tank, it still has 8-9 gallons left in the tank. That took some getting used to.

    When the light goes on for empty you still have 4 gal. When the needle is way past the line and your certain your walking, you still have 2 gal.

    Shit, mine goes on at 6 gal left in the tank. Takes like 19-20gal when I would fill right when the light comes on. Drove another 25mi on the freeway over the weekend to the next town where gas was cheaper and filled, still only took 21gal.

    Agreed with @Relentless
    Pretty sure it's 6G left when the light comes on..mine will never go on. My OCD makes me fuel up before that comes close. U never know.

    I had my light come on once. If I remember correctly it was only a few minutes after I left the dealer the day I got it. 20 gallons to refill.

    This is my 2nd Tundra. I had a 2011 I bought new and I was averaging about 19hwy/16city. I am wanting to do more to the truck anyway just trying to figure out what gets the best horsepower and mpg gains. I have a 2000 prelude that is all stock. So it gets all the work miles now.

    Manufacturers design in a buffer. From E to stuck on the side of the road.

    Don't wait till riding the light. Fuel is a coolant for your fuel pump.

    I'm rarely ever below 1/2 tank before I refill. Never going to run out of gas if I can help it.

    I got 21mpg on a 100 mile trip yesterday up and down I-81 around the PA/MD State line. You just have to watch the right foot.

    You know what guy's, I didn't buy a 4wd, 5.7L Crewmax thinking it was gonna be good on gas, I knew exactly what I was getting myself into, and you know what I don't care how much gas I use or my carbon footprint! I liked my truck the second I set eyes on it! I bought what I wanted. not what I needed, cause sometimes you gotta treat yourself otherwise what's the point of working, srapin & savin all your life if you can't do somethin for you or one of yours once in a while. CAN I GET AN AMEN!

    As you are aware, a dealer fill up is not even a 1/2 tank. It's 1/2 gallon.
