Boost is slow/sluggish. Added some chevron techron. MPG is still crap... used to live at around 17-18 around town...

    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...
  7. 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...

    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.

  9. 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...

  13. 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

    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...
