2002 Diesel with Superchip programmer

The truck is an automatic F-350. Has a Superchips tuner. Been told the truck
will get better mileage on Stage I than with the stock setup. Is this true?

Highly unlikely unless you change your driving habits.
Accelerate slower, drive slower, slow down slower...
But if you did that, you would probably see the same improvement even
without the tuner.

Once you get over the kick of having all that extra power, you'll get
better mileage...i still like to put my foot into it sometimes...like to
beat vettes and porches off the line at traffic lights...still a
teenager at heart i guess.

Watch the EGR temps though, especially if you're gonna haul or tow. Get
a big, fat exhaust system and a low restriction air filter system to go
with it and you'll be even happier (power and mileage) and less worried
about EGR temps...an EGR gauge wouldn't hurt either.

Re: 2002 Diesel with Superchip programmer

With all due respect, your response reads as though you don't have a
tuner and little or no practical experience. Changing the engine and
transmission parameters by using a tuner does provide better fuel
economy, especially when towing.

Keeping in mind that once the adrenaline rush from the performance gain
(i.e., being able to accelerate like a rocket) wears off the fuel
economy gains are realized.

More at issue are: (1) getting better air flow (intake and exhaust) to
help both economy and performance, as well as EGR temps and (2) what's
the ROI when you factor in the cost of the tuner and other mods to the
fuel saving cost.

If you don't do alot of driving and/or towing it may take a long time to
realize the ROI.

I can honestly say, from practical experience, that most performance
mods on a diesel engine also result in better fuel economy...the same is
not true for gasoline engines.

Re: 2002 Diesel with Superchip programmer

It's not my truck. We went about 150 miles yesterday with an empty trailer
to pick up a car. Went there set at stage 1, came home stock, but with about
2000 pounds more weight. Got better mileage on the way up, but that would be
expected. I was just curious.

This can be true but the way they do this is by changing the timing of
the fuel injection and timing is VERY critical for emissions control
on a diesel. If it were possible to get better MPG and make good
emissions, it would have came that way because auto makers are not
stupid. I am not say to no do it as it is up to you but it will
increase emissions and like someone else said, you need to watch EGT
closely if you "chip it" a lot.

Lots of varibles here too because you could have had a slight head
wind going and tail wind coming back too. You need to average it over
the same run a few times to get a real world average/change. Even with
my gasser I sometime get better coming back than going or the other
way around with no changes.

Re: 2002 Diesel with Superchip programmer

I applogize Big Al, my response was meant to refute the reply of 351CJ
and not directly reply to your original question. Again, I appologize
for the confusion.

I still stand by my post regardless of the subsequent posts by SnoMan.

It's not a matter of being stupid, it's a matter of satisfying the
average customer, meeting the minimum federal requirements, and making a
profit. I offer the following...

It's counter intuitive and defies the laws of physics that increasing
fuel economy also increases emissions. By definition emissions are the
by product of the combustion process comprised of the gases and
particulates. It's the inefficient engine that produces more emissions,
not the efficient (i.e. better fuel economy) one.

Additionally, tuners do much more than changing the injection timing.
They fiddle with many engine and transmission parameters. It's the
proper fiddling that produces the gains...one perceived downside is the
stronger shifting...some folks don't like that, but it's actually better
for the trans and the fuel economy.

Re: 2002 Diesel with Superchip programmer

Big Al,

What engine do you have? I have a 2000 with the 7.3L Power Stroke and
it has the Superchips tuner. I know from personal experience that I get
an additional 2-3 mpg's with the tuning installed, as long as I drive
the same way. I drive very conservatively, which also helps with fuel
consumption.

The above mpg increase applies to towing or not. However, I am towing a
very heavy trailer near the max of the F-550 stock ratings. If I am
towing on perfectly flat roads, I leave the tuner in. If I encounter
even moderately large hills, the tuner will make the engine overheat
much quicker, so I generally return the truck to stock before towing. I
have EGT and transmission gauges to keep an eye on the temperatures.

By the way, my truck has a 4.88 rear differential.
