I came home from Iraq in March of 09. About a month after I was home i bought an 06 Super Duty, 5.4l. She gets about 13 mpg. Id like some advice on improving gas mileage.

I come home from afghanistan sometime in April. Im planning on puttin a K&N FIPK, a throttle body spacer and exhaust on it, I wasnt true dual exhaust that exits in from of my rear tire. I want it to sound nice but also improve fuel economy. Perhaps magna flow high flow cats and flow master 40 series mufflers, 3 inch pipe. Havent decided on stainless or not.

Im also lookin the N-FAB prerunner with 3 9 inch Hella lights.

And i know this isnt economical for fuel, but shes gettin 35x12.5/R17 BFG Mudterrain KM2's.

Any thoughts, ideas or improvements welcome.

Id post pics but i dont know how.

 

thanks for serving, the exhaust should sound good with setup your lookin at

 

Skip the throttle body spacer, don't forget a power programmer...

 

Welcome to the site! Yes, forget about the spacer, a waste of money. Look into a tuner as the best bang for the buck.

 

Thank you for serving and welcome to the site.

 

You have a very heavy truck with an engine that's a tad too small for it - it's not going to get good gas mileage no matter what you do to it. Any lift, bigger and/or more aggressive tires, and things that stick out into the airflow and reduce aerodynamic efficiency are just going to make it worse.

 

What is a good tuner/programmer. and is that exhaust going to improve fuel economy

 

Power hungry performance = Gryphon and they carry SCT now I believe
Troyer and VMP are also using SCT products check out the Programming section lots of good info in there. I have a Gryphon from PHP and couldnt be happier

 

How much additional power can one to expect to get by tuning a 5.4?

 

Id like to say thank you freakyFX4. because of you im spending way more money than i wanted to. Id been lookin at the bumper you have, vs the prerunner. But, when i saw it on your truck I made my desision. So Warn HD with brush guard it is. But i think im going to put 4 of their SDB-210 Dual Beam lights on it, instead of hellas or piaas. ill put them on 2 switches, so 2 can be on spot and 2 on flood, or all on one or the other.

Now i just need to find a place to do the exhaust, find a tuner, buy the tires, recon smoked can lights and order the intake. Itd be nice to find one place to do all this before I come home. Here is about what ive found for prices so far, know anywhere to get this stuff cheaper.


And thanks to everyone for the appreciation, it mean a lot.

Warn HD Bumper 2300
warn Lights(4) 1000
Recon Cab Lights(5) 90
KN FIPK 300
KM2 1200
Exhaust 2000
7390
the exhaust is just an estimate, im hopin itll be done a lot cheaper, and i still need to price a tuner

 

I just took a look at the Bully Dog Triple Dog GT Gas Gauge Tuner. For 460, I like it

 

$2000 for an exhaust? That thing better be gold plated!

For the same price-ish, you could get a custom tuned Gryphoon from PHP, which will offer more power.

 

I look into the gryphoon. Im alotting 2000, just to over shoot and its stainless steel true dual with 2 cats and 2 flowmaster 40 series mufflers, so i know it wont be cheap.

 

will 35's fit in my wheel well without a lift or a leveling kit

 

You'll need a leveling kit and aftermarket rims.
