14 Ecoboost.
I had a bulldog on my old truck and it did give me some extra power and a little better fuel milage. The only thing I bring up to people when I have had people ask me is that make sure you restore computer before taking into the shop for engine problems or what not. I am not sure how much it improves power or fuel economy but I didn't buy my first one but I probably wouldn't buy one myself because it didn't help my 07 enough to make me feel like it was worth the money. They may be different know and if it was a sign octant difference I would be more likely to buy one.
