So, heres the deal.....I just got my 2013 FX2 with the Ecoboost and 3.31 gearset in the rear (stupid decision i know!)
Once the turbos spool im gone and great acceleration! But off the line its a complete dog!
What are your opinions on changing out 3.73 or 4.10 gears? I do mostly city driving and the odd Highway vacation....

 

If you can stand to take a slight hit in the MPG, I'd say go 4.10

Have 3.73 in my FX4 5.0L and IMO the gas mileage is acceptable.

What's your mileage like? city/highway?

 

15-16 (worst was 14 this past winter) / 18-20 (best was 22)

Tend to be a spirited driver.
