I have a 2005 150 Crew 4x4 Lariat with the 5.4 . Question is I now have 21,000 miles on it and I am not impressed with the power at 14 to 15 mpg. My wife has a Tahoe at 17 mpg with the 5.3 it that has alot more pep than my 150 can anyone explain or have a idea ? comments ,questions or suggestions ?

get a edge tuner and hold on.

An air intake will def. help with thorttle response.

and your right foot will help with the millage, I'm just guessing, but I would have to say your wife is easier on the gas than you are (just a guess, lol. I know plenty of lead footed women) and a tuner, intake, and exhaust will free your truck up quite a bit.

Tuner , air ,etc really wakes the 5.4 up ? If this is true why does Ford detune them ? I have thought about a tuner but am jus a little apprehensive with some of the tranny problems I here about and with fuel going up and up I would rather not pay for high octane fuel

B/C ford didnt spend the time and money to truely get all the power out of these trucks and if they did they would have changed the intake and exhaust.

14 to 15 mpg is this good or can it get better with a air,tuner combo ? Thanks for the info

Thats ok mileage....the tuner and Cai will help your mileage but it wont be worth the money you spend on the mods themself.

Is there a tuner that wont tear the tranny up .I have seen people talk about Edge , Xcal2 they seem to be the top 2 your opinion ?

Those are def. the most popular.
