I am a little concerned that my highway mileage which is suppose to be 19 MPG has not been attained. In the past, on any new vehicle which had a highway mileage listed with my type of driving was easily met or beat. Any ideas on improvements for gas mileage.

 

Let me guess you got the quad-cab, cause i got the regular cab and mine is a 2003 with a V6 and i get 24 miles on the highway and the sticker said 22. but one way to incease milage is go get a new igition computer, MSD controllers are pretty good, get the fuel econmoney one if thats what you wanna get. and then a new fuel pump and coil might help.
