A mild tune will help mileage. If I can help with any questions let me know.

Throw an exhaust on it and a PPE Economy and you will get 2 extra MPG.

AMSOIL Synthetics and fuel additives can help with mileage and will save you money on oil changes. If I can provide you some information or a quote, don't hesitate to ask.

Take care,

One way to save the fuel is to keep it under 60 mph. I know this isnt always an option but I have a similar trip to work and the speed limit 55. If I keep it under 60 and dont gas it then I usually get about 21 to 23 mpg. Once I break about 61 mph my mileage drops to about 19 to 21. If I break 70 then im definitely in the 16 to 19 range. Now my truck is alot lighter than yours but it should help. And definitely get a better air filter. Just a K&N drop in helps until you can get a cold air intake. The bigger exhaust helps some. And definitely tune it. Thats pretty much all I have on my truck.
