My truck is not stock anymore... I have the mods in my sig... The 20mpg was on a stock truck...

 

I get about 14...

Dont chip it expecting to get better mileage, you will be disappointed.

Throwing a chip or programer on it "can" lead to better mileage, but 9 times out of 10 it does not.

Lower your truck, put smaller tires on it, over inflate the tires, keep the RPM's under 2000...

 

What about changing the gears to 3.73's from 4.10's? Has anyone done this? James

 

You will never recoupe the cost of doing the gears... Your going to spend $2000 or more to swap gear sets...

Its like people who drive 10-15 miles out of there way to get 4 cents a gallon cheaper Diesel... You will never recoupe the cost.

 

dont over inflate your tires, you will lose it in the cost of replacing tires by wearing the center of them fast than the edge, keep them at rated psi an keep you foot out of it, my opinion mod at will your going to get best results with moderate driving habits

 

I am guilty of this 1, I will even calulate the mileage to and from the station, compare it to a closer station, figure in my fuel mileage, mileage on the truck, the difference in the cost of fuel, say 8 cents, and still drive 13.47 miles out of my way for the cheaper fuel, LOL.

 

Good info.

 

mods shown below.. before those i got 13-15 goin down the highway at 75-80 and bout 10-11 pulling.. after i get 19-22 and 16 or so pulling.. lemme remind you those numbers only show when not romping on it

 

I assume that those numbers came from the overhead display. If so, I think you should calculate the mileage manually (miles traveled divided by gallons used). I suspect that you will be humbled by the results.

 

GEES, way to burst a bubble. LOL.
