Fuel savers

Ok with gas prices being as high as they are and still rising I just wanted to know some options and possibly mods to help save gas.

So far the usual being fass, injectors, chip, possibly turbo. All used in moderation can help save gas, but what else can be done to help fuel milage?

Im sure this post will be kinda helpful for some, especially for those in places where diesel is pushing 4 bucks a gallon.

1.Synthetic Oil.......
2.Get rid of your fan if you don't need it and
3.maybe cardboard in front of the radiator(that's what I've done, do whatever it takes to stabilize your temp)
4.Make sure your truck is properly alligned. That's a big one. If you want demo on how much your allignment can drag your truck down. Push your truck in Neutral with correct alignment, then push your truck with the toe set really far in. You'll get the picture pretty fast.
5.Tire PSI.
6.Evans Waterless Coolant.
7.Truck bed cap/Aerodynamics
8.190F Thermostat
9.Make sure your engine is plugged in whenever possible
10. Keep your speeds down, the truck isn't aerodynamic and that hurts MPG
11. Intake Elbow
12. Tires make sure your tires are ok.

That should get you started.

Nothing helps these things out with their gas mileage.
Diesel is a different story. I'd start to use the term "fuel" it's more politically correct. Espically in a era wear alternate fuels are now being used.

Everything Philly just said and...

Try and keep you Boost below 5 PSI and your pyro below 600*F...
For every 5 MPH over 55 MPH your losing about 1 MPG!!! It takes fuel to create heat and the more pressure the more fuel!

* Straight pipe exhaust
* BHAF or similar
* Smaller tires (235/85 R16 or smaller yet)
* Reduce your height.
* If you got a Edge Comp 4x4 is the best setting for MPG (Most timing at low boost)
* Keep the weight out of your pickup... Don't haul junk around with you.

WRONG! There is no addition timing or fuel delivered till you exceed the de-fuel mode.
(Sublevel and boost pressure)
1 = 20 PSI
2 = 15 PSI
3 = 10 PSI
4 = 0 PSI
5 = 0 PSI

So you need a sub level of 4 or 5 to be out of de-fuel mode... This information came from Edge Tech Dept itself...

The de-fuel modes was made for larger injectors and laggy turbos so you could control your smoke.

I disagree. on my truck when im rolling down the road i can turn my from stock to 1x1 and hear a little increase in timing rattle. It starts adding timing on every setting, but it doesn't reach its max levels untill it gets to that boost pressure.

Funny...

I'm just relaying what I was told from the Techs at Edge... As for timing there is no extra timing till you exxceed the de-fuel mode.

But when I check with my ScanGauge II my MPG number goes up instantly when using sub-level 4 or 5. The highier the main level the more timing... So 4x4 and 5x5 give some good MPG numbers...

So if I switch back to 1x1 I lose roughly 3-4 MPG instantly... (Loss of timing advancement - Cruising boost is about 2-3 PSI at 65 MPH)

You might want to get one of these ScanGauge II's they really do settle a lot of myths about performance parts...:Thumbup:

The data is live data straight from both ECM and PCM computers...

How about if your running j/a, would level 4 or 5 be the best for "fuel" milage?
