I just traded for a 2006 F150 w/ the 5.4 Triton engine. Any suggestions on how to improve my gas mileage?

 

Cold Air Intake- S&B is the most popular
Programmer- Xcal 2 or 3 custom tuned by VMP or Troyer.
Gryphon from Power Hungry Performance (basically edge recased with custom tunes)

 

if i had to start modding over again this is the order i would go.

1st E-fans
2nd intake
3rd exhuast
4th tune
i just have fans intake and exhuast and those 3 gave me alot better gasmilage with my 4.6L when i frist got the truck when it was stock i was getting 10MPG!!! now i get right around 20MPG city...no one belives me but i do the math right and thats what im getting. good luck

 

one question. HOW!? did you install efans yourself?

 

took a punch and a hammer and took off my clutch fan got a fan from the junk yard zip tied it to the radator ran a wire from the batt to a switch in the truck then out to the fans. grounded it to the radator support. Very easy to do and very cheap only 30 bucks at my local junk yard for any fan set-up i got the lincon mark 8 HUGE fan. its about 3500CFM it cools the truck off pretty quick they say for our motors to have about 4,000CFM but ive never had a prob with this fan. the clutch fan was a PITA to get out i took it out and when it came out i threw it as far as i could i was so mad lol. its really easy and prob freed up about 15-20HP i felt a deff in power for sure. Theres some pictures for you
