Fuel Mileage

[alcat]

What should fuel mileage be for a stock 05 3500? I am getting 14-15 and have gotten about 18-20 in town. Will a programmer help? Automatic with 4:10 rear ratio.

No, that's about right. Perhaps a bit better than others.

For bone stock that is about rite, a programmer will help alot but the 4:10 gear ratio is goin to hinder your mpg a bit not much but a lil bit

What kind of programer

I run a Diablo Sport Predator, the smarty JR is safe for an all stock truck and they say can be ran without gauges....... both are really nice I have had good luck with my Predator so far

move up in tire size w/ those 4.10s . It will look better too

I've got the same truck with 4:10s and run a Smarty with intake, runner and 4"exhaust. I average just over 20 in town. Will have highway numbers in a week or so
