I just picked up a used (19000 mi) 2013 eco 4x4 screw 6.5' box and 3:31 gears. I really wanted the 5.5' box and 3:55 gears, but got a steal on this one that I couldn't afford to pass it up! It came with A.R.E brand Tonneau cover, spray in bed liner, Banks programmer, weather tech floor mats, AFE intake and heart throb exhaust! I will pull a 5000lb camper several times a year and hope it does well. Around town I'm seeing 18-20 if I keep my foot out of it. Anyone have exhaust or intake perhaps programmer? If so what's your experience?

I don't have exhaust or intake but I'm tuned. I have the SCT x 4 device with three 5 star tunes 87p/t, 91 p/t, 91p, I usually switch back and forth between the two 91 octane tunes and they are freaking awesome. 2nd gear scratch, pull hard, great power and Trans shifting.
My truck is a 2013 xlt 4x4 S.crew cab EcoBoost 3.31 gears with some suspension upgrades/mods
After the tune I won't be doing much more performance wise, it's perfect.

I've seen great stuff about the SCT but don't have any experience with it. Might sell the Banks and try the SCT though.

It pretty much seems to be the go to with the ecoboost, also multiple tuners write tunes for it so there's a good selection of custom tunes to chose from.

Lol ya I'm gonna look into it for sure. I really like it has gauges.

You'll do fine. I pull twice that weight with 3.55. Approaching 10,000 pounds I get 9ish mpg.

I have 3.31 and while I wouldn't say I have regrets. However, I would LOVE some 4.10's. So far I haven't seen too much power issues and my MPG is great (20+ highway). I also haven't done extreme towing.

I traded in a 2012 xcab 5.0 with 3:55 (drove for 2 years with 33,000 miles) for a 2014 xcab eco with 3:31. Both trucks were 5 star tuned with 87 p/t. The tires lose traction with the eco so much easier than the 5.0. The 3:31 on the eco has plenty of power and average 17.8 mpg with a heavy foot. On the highway at 70 mph average 23-24 mpg. That is my 2 cents.

My 2011 2wd had 3.55s but I did not tow with that truck...ran great and pretty good mpg.


My 2012 4wd has 3.73s with 2" lift and 34.25" tires and I tow a 29" TT...no problems.


With the low 1st gear and 6 speed trannies...I would think that even the 3.31 on stock diameter tires would be just fine.

I have a 2014 XLT with 3.31 gears.
My Dad has a 2014 FX4 with 3.73 gears.

I consistantly get above 20 mpgs and my dad can't get higher than love 17s. Both of us use our trucks to mainly commute with maybe a little towing / hauling on the weekends. Next time around I'll get getting the lower gears as well for sure.
