Well, it is not what I've heard, it is what I removed on my 2K. It makes
abosolutly no difference in mileage. Believe me if it did I would remove it
on this one as well.

That's not what I've heard, but what ever. If its the venturi shaped
silencer, it's a restriction.

A diesel is going to burn "x" amount of fuel to turn the engine a certain
rpm, since rpm / power is fuel volume dependent. Engine design can be
improved and there are more efficient engines available, like the
Phillips/Sterling.

It does a lot of good, to a point on diesels.

The silencer doesn't do a thing other than cut down on a whistle.

I'm of the belief that with regard to mileage, the makers have done pretty
much all they can do with the Cummins and keep it epa compliant.

True, when people don't bother to reduce the intake restrictions (the
infamous silencer for example on some diesels) or improve the exhaust
systems. Improve those and you can see an improvement in economy.

This is one thing I'd really like to take the EPA to task over since there
are many little tricks that do improve economy of an engine and the
performance considerably but may not be as ecologically horrid as the EPA
claims. Water injection is one item, for example on gasoline engines , that
improves performance, reduces octane requirement and reduces oxides of
Nitrogen.

In today's engine it means lean. It is all 'putor. The edge fattens up the
fuel, dosen't do a thing for air.

When I rebuilt the 318 in my old D-150, it had been getting a consistent
14.5 mpg on the highway and about 11 mpg around town.

That was with the 2 bbl Carter emissions carb, dual plane EGR intake and all
the smog equipment. In the rebuild, I kept only the PCV. I used a 1972
calibrated Carter carb and the single 2-bbl intake from a 318 72 Dart.

In theory, because both main jets are now feeding all cylinders instead of
each jet feeding half of the cylinders, my gas mileage should have dropped.
to about 10 or 12 on the highway. With duals, my son gets 26 mpg highway

Instead, I gained 10 mpg on the highway (24 mpg) and 8 mpg in town (19 mpg)
on 89 octane fuel.

More fuel doesn't mean less mileage if you have more air to mix with it.

Please explain how using more fuel will increase your mileage. Please tell
us more about this truck, tires, rear gears, transmission, 2wd or 4wd.

Imo All these mileage improvement things are just to get ya to spend your
money. All ya can do is tune it, change the fluids and filters regularly,
keep the air up in the tires and drive like there is a egg under your right
foot. Remember it is a truck.

I know that you can adjust the computer for more horsepower, but can you take some power out of it to get better fuel economy? I'm 40, and dont care about all the power but want to save some on my 14 miles to the gallon highway. If you can how or who can do it. (please dont sugest the dealer) Richard
