I have the 3.5 ecoboost and I really like it. However, I hear the 5.0 has more gratification when it comes to engine sound. I can hear my turbo whistle occasionally unless I am just driving with a lead foot for fun.
Just built what I think I'm going to order, but 2 things bother me....
- in order to get the 3.55 gears, you have to add the Pro Trailer Backup assist which is $1465. Might not be worth it now.
- no place to delete the Platinum badge on the tailgate. Will have to make sure the dealer puts that code in when ordering.
I'm going to want to change tires from the 275/55/R20 to probably 295/65/R20 after I level. How much will I miss the 3.55 if I stick with the standard 3.15? It's also a bummer only one wheel choice on the Platinum.... again.
Still not sure on the 3.5 or 5.0

I can't say that I am an expert on this sort of thing, but I have been reading several posts about bigger tires and gear ratios and I don't think you would like it with the standard 3.15. I have a 3.31 and I am already worried about how performance might be affected by added tire weight. If I could change one thing about my truck (that wouldn't be changing it from XLT to Lariat) it would be to have the gear ratio at 3.55. It might be $1500 bucks for Pro Back Up trailer, but it would be just as expensive or more to get the gears changed and it wouldn't be factory warrantied.

I'm in the same boat right now. I'm thinking with a 2.25" level 275/60R20 would be about the limit that would fit without ANY trimming. I think if you're gonna go 34" tires you may need a 3 or 4 inch lift. Anyone else have thoughts or have a similar setup already?
