Gasser Question! Please Read

[lcducote]

My 17 year old brother just got a 07 F150 and wants some extra horses.. I don't really know too much about these newer model gas trucks. I was wondering if any of you have owned one in the past and would be able to help me out.

We did cold-air and exhaust.

What are the best programmers/chips for a 5.4 lt..???

[mazsecond]

The only way to get a real noticeable power increase out of the 5.4 is a supercharger kit. Chips on gas engines are not the same as diesels. You won't be getting 100+ HP increases. Supercharger is the only way to go. Roush is probably the best for the 5.4. Heck, thats whats on the Foose F150! And the roush edition F150.

im going to dissagree a bit with mazsecond...

i had a 2008 5.4L F150 and i saw a very noticeable diff when i added a edge evo and an intake to it....

mpg went up almost 2mpg as well... i actually still have the S&B intake that i had on the truck for no more than a week before i traded it in....

edge chip from PHP, intake, exhaust. thats really it until you go big. for superchargers your main options are roush and whipple

[lcducote]

cool!! i do not think we will be putting a supercharger on anytime soon.

I realize tuning is not as beneficial for gassers but we were hoping to get 30-50 extra horses out of the deal. With the exhaust and cold-air I think we will be right around 75 extra hp.

You won't make 75 extra HP with tune intake and exhaust but it will be very noticable. Go with php tunes, bill is very good with those trucks. Go check out the php forums there are some knowledgable people there when it comes to the f150.

Bill has some great tunes for that 5.4 for sure!

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.
