The Edge on a 5.4 is good for 25 to 30 HP and I think the 4.6 is supposed to be a little lass than that. However, 25 HP on my 5.4 was BIG and the shifting improvements were awesome.

 

I'll take your word for it.

I'm in Gainesville, FL. Tifton is where I bought the tuner.

The problem with returning the Evo and buying a Gryphon with custom tunes is that if I am still unhappy with the results I am stuck. I doubt that custom tunes are refundable, because they are just that...custom.

 

true, try and find someone with tunes on their truck, doesn't neccesarily have to be a f150 but just to give you an idea on the improvement, just run theirs stock and then program it to their custom settings and i think you would be happy and willing to spend the cash

 

Your not gonna feel like it has a 300 shot but a small improvement over stock especially the shifting. im not thrilled with mine but it gets better mileage then stock and actually downshifts when i need it to.
