How much would my fuel economy improve if I did this to a 96 bronco?

first of all do they make fuel injected broncos because I want to maybe put an edelbrock pro flo efi in it. Then I would put a bully dog tuner, a banks super scoop cold air intake whatever its called, and a turbo then maybe a 3 or 4 inch exhaust and straight pipe it. Oh and is the fitch fuel catylst a good product I think that good help my gas mileage to.
