EcoBoost 3.31 Owners...Any Regrets?
#51
2013 eb screw 3:31
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?

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.

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.

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.
