Turbo chargers are a good way of getting power that you don't really have. The Eco boost will give a 4 banger the power of a 6. But, In my opinion, I think it will shorten the lifespan of the 4 cylinder.
I'll stick with the conventional 6cyl. My 11 limited has no problem getting up to speed
(I may think differently if they were putting a 6cyl Eco boost in the edge)
