Read on the f150Forum that on 4.6 it does not increase MPG or HP.
But on the 5.4 some said you will get 20-30 more mpg per tank, which is like 0.7-1.1mpg increase.
I am guessing this will only be in the summer time though when you do use your AC.
And as for the HP increase with 5.4, I doubt it would be anything noticeable, all it is doing is freeing up a clutch.
The biggest outcome from this would be to lessen the miles on your water pump.
I would spend no more than 200 on a total setup.
I do plan on doing this mod tho on my 5.4
