MPG on 2004 F150 S/Crew
#16

#18
I did notice the mileage got better after about 10k on the truck. I have 18k on it now and average 15 mpg. I also put a top cover on which helps my freewy driving tremendously. I average 18 on the freeway when doing about 70 mph on long trips. You should see your gas mileage improve with time. Also....make sure to keep reseting your odometer trip settings after refilling.
Hope this helps!

The EMS constantly measures fuel to air ratios, so I would assume that it would adjust the mixture according to what the oxygen sensors tell it. In other words, the computer would compensate for any changes done with the intake...

One thing I do know is that my 04 gets about 10 to 15% better fuel economy on the highway than my 02. The other is that I don't think my 02 did its best until it had about 10,000 miles on it.
The best my 02 ever did on the highway was 19 mpg (Imperial) while my 04 has already checked out at about 22 mpg (Imperial). These numbers would equate to about 15 and 18 mpg (US gallons).
By all means try the mods you are considering, but remember you will not likely get the full effect for quite a while until your engine loosens up.

If you want the super-chips for performance gains, by all means - go for it. If you're really interested in saving money though, do a cost-analaysis.
Superchips $350 (a good price)
K&N $40
Premium Fuel .15 more per gallon.
Considering you gain 2mpg AVERAGE, it breaks down like this.
15,000 miles unmodded (12.5 mpg avg) @ 1.91 per gallon = $2,292 in fuel
15,000 miles modded (14.5 mpg avg) @ 2.06 per gallon = $2131 in fuel
An annual savings of $161.00
It would take 3 years to break even.
Now, if you're using the gas milage argument to convince the wife the Superchips Tuner and the K&N is a good idea - it's our little secret. But when you do the math, you're paying for PERFORMANCE, and not better gas milage. Very few mods will ever pay for themselves in milage savings.
This is also taking into consideration that you can keep your foot out of it...yeah right!
Just my .02 (or most like $161)

OK,
Just spent $253.00 on the K&N cold air intake part# 63-1089. I won't have time to install it for a week. I used to own auto shops years ago (1979-1986) out in Cailfornia. I am a bit of a motorhead and absolutely LOVE working on cars/trucks. I even have a 3 bay garage with lifts at my office to maintain the service trucks for my current business. So it is not that I am a rookie writing all these messages, they are driven by GUILT. I always preached to stay away from bolt-on accessories. I know if you want to get more air/fuel in and out of the engine faster, change the cam, increase valve size, enlarge and tune the breathing paths ie intake and exhaust.
To put it in a nut shell, you guys can have a laugh on me. (and at my expense)

Ford is selling these trucks for their civilized nature and consequently quiet operation is valued over performance. The fact is these are close to one horsepower per cubic inch engines and with a few bolt-ons they should easily achieve that level.
The other nice feature of the 5.4 is its torque curve and once again helping it to breathe better has got to increase torque.

Mainly, I think I'm like you in that I hate to run a completely stock set up.

Ford F-150 4x4 MPG
Just took delivery about a month ago and only have 1200 miles on vehicle Lariat F-150 4x4. I live in upstate new york and have a mixture of city and highway travel. I've been averaging between 17 and 18 mpg with the 5.4L engine.
I have noted that if you get right into it, the mpg goes down to 15 mpg and over 60 mph it drops off to 16 to 17 mpg. By avoiding jackrabbit starts and letting it coast when ever possable I can get all round about 18 mpg.
