I have a "gasser" Chevy Silverado with a 5.3L V8. I had true dual exhausts (Flowmaster 50 Series) installed - which probably gave me a little bit of horsepower. My next move includes new spark plugs and a cold-air intake system.
I wager I will get a total horsepower boost of 25 or 30 at the most, sans chip. That is the result that my neighbor got with his 2006 Silverado with a 5.3L engine. He took it and had a 'before and after' dyno reading done on it.
The previous poster is correct about gassers not benefitting from "chips" the way diesels do. I assume that is because of the compression ratio differences. Most gassers are 8:1 to about 10:1, while diesel engines are 18:1 on up to 22:1 or so. Diesels handle compression and pressure that would make a gasoline engine turn into Cheez Wiz!
P.S. Good luck with your Ford, though. I drive a Chebby, but will always have a soft spot in my heart for Ford trucks - particularly the Super Duty line.
