I have tried Cold air kits, 3" exhaust, and performance chips, to no avail. 14-15 mpg is the nature of the beast. Save your money on performance upgrades and save it for another vehicle.

Nope. You either need the utility of that vehicle and take the trade-off in lower MPGs or you don't. Which is it? I'd like my F150s to get better than 18-19 MPGs doing daily driving, but I can't pull too many trailers and take 4-5 other people with me with a Prius.

If it could get better economy than 13 city, 15 combined, and 17 highway Toyota would have done it. CAFE puts tremendous pressure on mfrs to produce the best fuel economy practical, at least without killing the engine and making it put out tons of NOx. The chips are good for shortening the life of the engine and not much else.

It is a V-8, it will drink gas. Get a Tacoma.
