Requesting Advice

My wife has a 2010 F150 with the 5.4L. The mileage isn't that good on it and we would like to be able to do some mods that might help with mileage. Can anyone suggest what we should do? I was thinking of an exhaust, cold air intake, and maybe a chip. Please advise as to what you think would be the best items to put on this truck.

Is it abnormally low? What kind of mpg are you seeing? A 5.4 is no known for being a fuel miser...

Remember your right foot is the best way to control mpg's. An intake, exhaust, tuner, etc... add up to a lot of tanks of fuel. For the teeny tiny mpg gain you see on a $300 intake would take a long time to pay for itself.

Your best bet would be to keep on top of maintenance, use synthetic fluids front to back, and drive like a grandma.
