I had a tuner on my last F150. Didn't do squat. You can do more with a tuner on a turbo motor. But honestly, I would have huge reservations about putting a tuner on the Eco. It'll void your warranty and these tuners haven't done any long term durability testing.
I HAVE seen youtube videos of "tuner" Ecoboosts doing some phenomenal accelerations.
