Big Red 97'

Ok well I decided that im gonna leave my 4:10s alone. Now does anyone know how I can get BETTER FUEL MILEAGE??? I have a 97' so a programmer is not an option. Im already running cld air intake and straight exhaust. What else can I do? 13 MPG just isn't gonna cut it at $4.00 a gallon. Please Help!!!

I'll bite, what does "injector pump turned through the roof " mean. Did you adjust the AFC screw, change the timing, change the plate, what?
All that smoke you are so proud of is unburned fuel, by the way.

Air up the tires to 75-80. Cheapest mpg improver there is.
The wear is more than offset by the cost of gas savings.
As for ride...well it is a truck so might as well ride like one.

The areas that hurt mileage are: drivetrain, rolling resistance, wind resistance, weight(only affects when accelerating or pulling a hill). The biggest factor is wind resistance on the highway and it is weight in the city.

To decrease wind resistance, the easiest thing you can do is slow down. These trucks do a ton better at 60mph than 70. Beyond that, you can get rid of anything like light bars, headache racks, stacks and that sort of thing that disturb airflow. Also, you can lower the truck and put on a larger air dam. If you are running large tires, these will kill you because of raising the truck, more windage, more rotational inertia, and more rolling resistance.

Weight is not easy to cut on these trucks if you still plan on using it as a truck. Tires is a good place to cut weight(more importantly rotational inertia).

Motor mods won't get you terribly far but they will get you a little. A little more timing can help. People are also reporting good results with DDP injectors. Otherwise, a stock setup is probably about as good as it gets, if you are dumping lots of fuel, it won't get good economy.

Then there are tons of little things that add up like dragging brakes, dino oil in differentials etc.

The cheapest and easiest thing to change is your driving habits. Don't accelerate hard and don't drive fast. Anticipation is the other important thing.

Instead of air try Nitrogen in the tires, lighter and gain .5 to 1 per Gal. about 20 bucks a Tire here

You say you have gen3 chromes.. is it chrome steel or chrome alloy? Moving to the alloy will save rotational mass and allow the engine to use less power to get you moving.

4.10s are a big culprit. When I ran my 03 I had 37s and 410s. Had I kept the 3.92s I wouldn't have dropped to 11mpg.
