I would hope so. I would happy to get 422 miles on a full tank. I need to invest in a Titan fuel tank.

 

yeah i have a 34 gal tank.that was highway.running around town im getting 500-550 out of a tank.its about 17mpg.

 

500-550, that's awesome in my opinion.

 

im able to get 450-500+ out of a 25gal tank(18-22)

 

What's done to yours to get that mileage?

 

LBZ is a solid duramax. little to no probs with them. upgrades...... intakes with scoops (S&B or Banks), intercooler and tubes (Banks or PPE),

Tuner: depending on what your looking for, i would go with Banks 6 gun and the Banks monitor, but i also like Bully Dogs GT because both have the ability to monitor exery aspect of your truck, including MPG on the Bully Dog, also your not looking for an 800 hp+ truck so it would be pointless to get some complicated tuner. NOTE...with your tuner you cant just go changing your settings when ever you feel froggy. the truck has to get use to the tune. if not, your going to F'up your truck (you may know this already, but hey just for ***** and giggles)

Exhaust (MBRP, Banks, Diamond Eye)

If your are going to be towing alot or long distance traveling, i would suggest purchasing the PPE Transmision, Engine, and Differencial Deep Pans. More Fluids= Cooler Temps=Happy Truck.

gopurepower.com has reusible oil, fuel, and trans filters. they perform better than ur avg auto parts store filters and dam near pay for them selves after a year or two. they have 1 million mile warranty on them and literally you pull them off, clean the out and throw them back on your truck. prices are $200 for trans, $240 for oil, and Fuel is $300
