Well I have been contemplating trading my '10 Tundra in on an F-150 for a few months but didn't want to take the hit on the trade. I now have a buyer for the Tundra and have a little cash saved up to avoid carrying over any negative equity. I'm looking at an FX2 CC with the Ecoboost. My problem is I'm having trouble finding one with 3:55 gears. Most have 3:15 which I'm not really liking. I'm coming from a Tundra with 4:30 rear gears which is pretty comparable to my brother in laws Ecoboost with 3:55. I'm looking to hear from those who have a 2wd CC with Ecoboost that have 3:15's to see what you think.

Hey guys just wanted to let you guys know picked up my 2012 FX2 Ecoboost with Luxury package in Oxford White today. Interior is just unbelievable and the Ecoboost is really nice. Truck has the 3.55 gears and it really moves out. Got 19.2 doing 70mph over a hundred miles on the trip home. Gonna go take it out on the town now. Gonna try and post a pic.

I did an ad for a 2012 white FX4 with 20's yesterday and I fell in love with it. Looked sharp, great contrast of colors. It'd be my second choice next to black.

That's what I have. 2012 F-150 SuperCrew 4x2 with 6.5' bed, EcoBoost engine, and 3.15 e-locker diff.

Any diff ratio is a compromise. My intended use was to replace a Honda Odyssey as a long-distance highway cruiser, with comparable aminities such as leather interior, automagic AC, etc., but with enough tow rating to tow a 7,000 pound trailer on occasion. That's what I ordered.

The 3.15 is wonderful if you don't work the turbo too hard. At 60 MPH without the trailer it gets around 20 MPG. Speed up to 65 and it gets maybe 18. 70 MPH is 17 MPG. But the speed limit is 75 MPH, my normal crusing speed is 78 MPH, and my MPG is around 16. I expected better with the long legs of the 3.15 ratio.

I suspect the 3.55 would give better MPG at 75-78 MPH cruising speed, because the engine RPM would be higher into the HP curve and the turbos wouldn't have to work as hard.

I wanted the Max Tow pkg, but you have to order a 3.73 axle ratio to get that. And I was afraid that short of legs would kill MPG. But others with 3.73 ratio report better MPG than I've been achieving.

My tow rating is 8,400 pounds with the 3.15 axle ratio. The truck is plenty powerful enough to tow a 7,000 pound trailer over the Rockies, but it doesn't have enough GVWR to handle the hitch weight of a 7,000-pound tag trailer without busting the 7,100 pounds GVWR of my setup.

The max tow pkg comes with 500 to 600 pounds more GVWR, so that's what I needed. With 20/20 hindsight, I'm pretty sure your 3.55 ratio will give you better unloaded highway MPG at 75 MPH than I'm getting with my 3.15.

Towing MPG depends not only on speed but also on terrain. Going to Austin at 62 MPH dragging my 5,000-pound TT, I get about 10 MPG the first 175 miles, then it falls of to about 9 MPG for the last 125 miles thru the Hill country.

This F-150 Lariat dragging a 5,000-pound TT replaces a '99.5 F-250 XLT PowerStroke dragging an 8,000-pound 5er. Towing MPG is very similar. And on both, I get about 16 MPG unloaded on the highway. But the EcoBoost F-150 is a lot less buying price than the F-250 diesel, so th F-15o is a bargain.

So I'm satisfied with my choices, but I still wish it got betr MPG, both unloaded and towing.

Thanks for the compliments. I started looking at f-150's because of the ecoboost motor but I'm equally impressed with the interior of this truck. I can't think of one thing I would change about the truck. I can say this will be the first truck I have had that I will not be putting an aftermarket exhaust on.
