  4. Increasing MPG questions

    F150 Ecoboost Performance
    So I have a 2011 F150 Ecoboost, and I have a few questions about it regarding MPG. I want to preface this post by saying I understand a lot of it depends on driving conditions and the driver. 1. What is the best aftermarket intake? Is it necessary to have the vehicle tuned after putting...
  5. Poor MPG with new plugs

    F150 Ecoboost Problems
    Hello all, I have a 2013 model f150 ecoboost that I have recently purchased a couple weeks back and had the dreaded miss that is ever so common. I ended up replacing my plugs and boots with Autolite XP5363 (gapped at .030) and Napa brand plug boots because I didn't want to spend the $$ on...
  6. 2016 Expedition tuner/programmer/module for better mpg

    Ford Expedition Ecoboost
    I purchased a 2016 Expedition & overall I'm very pleased. It'll avg between 20-21 mpg on the highway but falls to 17-18 around town. I've had good luck in the past with tuners/programmers increasing mpg, I'm not looking to gain big hp I just want to see better fuel economy. I've been looking at...

    Introductions
    I bought my first truck last week: 2012 F-150, 3.5L EB, 2WD, 3.55 gearing, w/ 71k miles on it. So far I love it, but I'm concerned with the gas mileage I've been getting.

  8. Put the Damn Dam back on

    F150 Ecoboost Performance
    I took off the air dam several months ago. I noticed no difference. I was looking in to possible mods to get more air to the intercooler, and realized a few things. If you have facts or links to creditable sources, I would love to hear them. If there is anything we can do to get more air to...

    Going on a summer roadtrip around labor day. I have a stock intake, exhaust, and intercooler. All I have is an SCT livewire running 5* 91 tune. What would be the best use of my money to increase my MPG? I was thinking either: 1. New intercooler 2. Intake and Exhaust 3. Meth injection I have...
  12. Ecoboost MPG

    F150 Ecoboost Chat
    I recently purchased a 2012 F150 Lariat Supercrew 4x4 with the 3.5L engine and max tow pkg. I have been driving primarily in town and averaging 11.3 MPG. I towed our 5000# camper once on county roads and averaged 6.6. This doesn't seem right, any ideas or suggestion would be appreciated. Thanks

    F150 Ecoboost Problems
    I am considering an Ecoboost F150 or a 5.0 V8.

What is the prevalence of these. Is it something I really need to...

    2015 Ford F150 Ecoboost Chat
    Wondered if anyone who has the new F150 with the 3.5 Ecoboost has towing MPG numbers. I have a 30' travel trailer that weighs 5700# dry. Looks like that weight wouldn't be an issue for the truck to pull, but wondered what the MPG might be. I'm really hoping to get better than the 8-9 I was...
