I moved you post to its own thread because I felt it could be better responed to on its own!!
To gain fuel milage a tuner will be the best bet for the most gained cheaply, things like air intakes and exhaust might help but not enough you will really notice. The lb7 is by far the best of the d-maxes in the milage dept. already. a small tune like 40 60 hp would do you the best IMO and a 4"exhaust would complament it but not really needed for the most part!!
