EcoBoost 3.31 Owners...Any Regrets?
Just want to hear from the EcoBoost owners with 3.31 gears...do you have any regrets not getting another ratio?
From the Ford Canada site, the EcoBoost supercrew with 3.31 gears can tow 9,100lbs. The 3.55 tows 9,500lbs
Honestly...either of these numbers vastly exceeds what I will foreseeably tow. I'll be towing some dirtbikes, a few loads of gravel in a 1yard trailer, etc.
Mostly the truck will be used lightly loaded. Day trips to go fishing. Logging roads. Hauling a bed load of alder firewood.
I want good economy more than I want a rocketship. And I want the EcoBoost for it's quiet operation.
Thanks!

I'm not very familiar with gears. I have a 2013 ecoboost with the 3.55

I wonder whats different from 2012 as 3.31 axle had a limit of only 8100 lbs. I seen 2013 upped the tow rating to 9200 lbs so I wonder if it had something to do with the upgraded intercooler.

i actually have the 3.73's, because that was all that was available in an fx4 trim.
i'll say this, with the new 6-speed transmission i am in 3rd gear before crossing an intersection from a stop. and with the torque of the ecoboost i have no need to cruise 65mph at the rpm's it sees. it is nice when towing, but then again, i could just lock out 6th gear if it was needed while i towed because i had lower gears.
turbo's love low gears. lets the turbo's spool and load. i say go for it. i plan to on my next one.
edit:
when i say "low" gears, i mean low numerically...

Thats what nice about the F150 lineup, they give you more configurations than any other pickup. I think the 3.15 are better highway mileage to the 3.73/4.10 which are towing monsters. If your not towing but 1/2 capacity of your truck then you got the right gears. I tow a 21ft bass boat all year long so the 3.73 max tow was the truck for me. I liked the low end grunt when at a traffic light to keep up with traffic and not be the knucklehead everyone is screaming at becuase it takes too long to get up and go and there looking to pass me because i'm the granny in the fast lane. I wish my truck got the 19-23 miles the lower rears gets in mileage but it is all a trade off to the needs of the owner.

I've got a 2013 ecoboost 4x4 screw with the longer bed and the 3.31 gears. Got over 3000 miles on it now. Mainly daily driver stuff, no towing, 60-70 miles a day some hills and right now it's showing 18.0 mpg life time. At 2k miles it was 17.8 so it is increasing still. No problems, no concerns with power or anything. (These are all winter mileage / gas numbers as I bought my truck at the end of November.)

My 3.31
I've got the 3.31 in my '11 eboost scab with 21K miles. I get 21-22 @ about 65-70 on the highway. Everything is stock but I'm about to pull the trigger on a set of 295/18's and Bilstien 5100's. I wonder how that will change my torque, power and mileage? Anyone else have this setup or any thoughts? I really don't tow much. Was also concerned if I might have to eventually switch out diff gears but not sure to which one.
