***PWRSTROKETHIS*** · #1 (**permalink**) 03-25-2009, 04:54 AM

Im looking to try and make my truck a MPG king its a 02 7.3 automatic, My whole goal in building this truck is to get as many miles per gallon I can out of it with out sacrificeing power and even posiably gaining a little? Any suggestions on what you guys have used to get this on yours (Alot of you guys have some real street machines) I dont need huge hp gains or tq gains just as many MPG as I can get. I keep geting into a argument with a guy (he is a little bit

)here that says he can get more gas milage out of his 5.9 L dodge gas engine than I can out of my 7.3L

(I DONT BELEAVE THAT OWNED A 1999 Dodge durango and i only got around 16 city and highway)

do a diy intake(look in the mod section) and get some 3.5" exhaust pipe and straight pipe it.

After doing my mods, listed in my sig, I can do about 17 city(compared to 14-15 before) and around 20-22mpg on the highway(compared to about 17 before). Towing Im doing about 14-15 compared to about 12 before. All the city/highway driving was in Economy mode and the towing in Tow mode.

I'm gonna say your buddy is right. Comparing a dinky 5.9 liter straight six to a super huge 7.3 liter V8? Of course he can get more mpg and unfortunately he can make more cheap power too with normal daily driver type mods.

Our fords are better trucks and the 7.3 is a dang fine engine but honestly, I would prefer a 5.9 cummins under the hood of my superduty.

For mileage gains you can perform the 6637 intake (aka DIY tymar) and replace the muffler or whole exhaust system with free flowing parts. Then you get gauges before installing a chip from one of the vendors selling an economy tune.

You can get more extreme by going back to stock size tires, remove big brush guards, put the non-towing mirrors on, lowering, etc.
