 RECENT TESTIMONY:

Steve Shelley is the man! After struggling with a Diablosport tuner on my Chevy 2500 HD, i found that there are very few products out there which can actually deliver more MPG's. However, after finding Diesel Domination's website, i was sold on the custom tuning technology! Steve successfully took my truck from 14 mpg's to an average of 18 mpg's on the highway cruising between 65-70. ( My truck has a 6'' lift and 33's) Not to mention, my truck has a significant power increase. No BLACK SMOKE and a ton of torque makes it fun to drive. Thanks again Steve.


Sincerely,

Dear Duramax Diesel
Owner,

Finally you have found what you have been looking for... you don't need to keep searching. If 5-minutes of your time is worth saving over a $1000 a year in fuel costs... then please take the time to read this.

My goal is really very straight forward. To help you get the best fuel mileage possible out of your truck. To provide you with an actionable strategy to utilize your truck's hidden mileage potential just waiting to be tapped.

The valuable information on this website could be worth hundreds, possibly thousands, of dollars of yearly fuel mileage savings... IF YOU APPLY IT!

No where else on the Internet will you find the potential DURAMILEAGE has to unlock your truck's optimum fuel economy.

The truth is....
when it comes to better fuel mileage... YOU CAN HAVE IT!... and you don't need to spend a fortune on stacking expensive aftermarket products on your truck to get it. 


WHAT'S THE DURAMAX MILEAGE SOLUTION?

Five years ago the majority of our diesel truck customers were looking to increase the horsepower of their rigs.

In the 2004 diesel when crossed $2.00 a gallon... our customers suddenly began asking for better gas mileage over power. Now you can find dozens of products on the market making fuel mileage claims because of this demand.

For the longest time it seemed that almost every performance upgrade we did to a Ford Power Stroke or Dodge Cummins produced a fuel mileage increase.
 
With the Duramax however... for years we struggled to find a solution to that provided consistant mileage increases. None of these aftermarket products would pass the customer satisfaction test in the mileage area.

Then one day a customer informed me about his buddy's Duramax 
getting 25 miles per gallon. 

I immediately checked out if this was real and I learned this Duramax's fuel tables had been remapped to get this unusually high mileage. 

It turns out the developer who tuned this Duramax had engineered a proprietary method that gave us the ability to remap of the entire ECM fuel table...
which results in mileage gains of
4-7 miles per gallon.

Now you are probably thinking... "yeah right... 4-7 mileage per gallon sounds to good to be true".

Well it is true... we had found our solution and since that day we have tuned 100's of Duramax diesels using this proprietary method...
and the results speak for themselves!

We have nicknamed this high mileage ECM tuning DURAMILEAGETM.

 


SO WHAT EXACTLY IS DURAMILEAGE?

DURAMILEAGE is the product that will do all the things you were hoping for... that the others promised to do... but could not.

First off... DURAMILEAGE is NOT:

an off the shelf hand-held programmer

a performance chip that installs in the factory computer

DURAMILEAGE is the "recalibrating" of your truck's ECM with proprietary fuel maps that were developed by more than 25 years of GM automotive experience. 

The ECM, also known as the ECU or PCM, is the "brain box" that controls and manages the injection of fuel into the motor. It does this by using sophisticated formulas and feedback from several engine sensors to regulate the air/fuel ratios.

Properly recalibrating or remapping these "fuel tables" results in changing the "peak efficiency" of the motor... which in turn increases its fuel efficiency

In recent years manufacturers have set these tables to favor "better emissions" over fuel efficiency which has caused the fuel mileage of the diesel engines to drop.

When we remap the fuel tables on the ECM... your engine now has a faster torque rise at a lower RPM... resulting in a stronger "bottom end" power band. 

This significantly improves the fuel economy because the engine does more work with less effort.

Diesels are a workhorse engine and are designed for LOW-RPM... HIGH-TORQUE output. 

When the factory takes the power from the botton-end and moves it further up the RPM just to cut emissions... you also lose the power you need to get big loads moving out of the hole.

We have the capability to "Fine-Tune" over 50+ potential fuel tables and engine functions.

Our primary tuning option for the Duramax diesel is our High-Mileage Fuel Economy Tunes...
which also provide modest horsepower gains of 65HP for improved towing.
 
Also... we can perform High-Performance POWER Tunes and "HOT-Racing" Tunes (150HP+) that blow away any hand-held programmer's so-called "HOT" tune.

We individually customize each truck owner's ECM with an unlimited range of "tried and true"calibrations... resulting in wider variety of performance levels that far surpasses ANY aftermarket performance products currently available. 

With years of knowledge and experience selling diesel performance upgrades... I truly believe that our 
DURAMILEAGE tuning is the most effective and safest way to increase your Duramax's fuel economy by as much as 4-7 miles per gallon.

 

 

 

 

DURAMILEAGE VS. CHIPS

You may have noticed we offer Chips and Programmers on this website... that is because we like these products for what they were designed for.... to produce POWER!

To date... we have yet to find ONE product that consistantly produces higher customer satisfaction overall when it comes to fuel mileage improvements... than our DURAMILEAGE tuning.

While chips and handheld programmers do provide performance gains… what you need to understand is those increases are normally made by changing only 1-2 engine parameters (injection pulse & timing) that ADD more fuel to the engine... and usually only produce real horsepower at the higher end of your RPM range which can also create higher exhaust gas temperatures.

On the other hand... DURAMILEAGE tuning gives you additional Horsepower and Torque gains across the entire RPM range of your vehicle... along with the fuel mileage gains.

Our indepth level of tuning allows us to precisely calibrate nearly every fuel map and engine parameter on your ECM. 

It is the difference between using a sledge hammer versus a surgeons scaple to custom tune each ECM to the customers needs. 

This ability to tune literally dozens of engine parameters produces overall performance results that far surpass other aftermarket products.

For example... our own 2005 Silverado Duramax Dually 4x4 only averaged 14 miles per gallon when we first bought it. 

Using hand-held programmers we were not able to raise the mileage more than 1-2 miles per gallon.

But... after turning with DURAMILEAGE “tried and true” high fuel mileage calibrations… the truck increased to 20 miles per gallon at 65MPH running empty. (that's with an 8000 lb dually) 

We averaged driving the truck 25,000 miles a year. W
ith today’s fuel price of $3.50 a gallon that means with a DURAMILEAGE tuning installed... we saved nearly $1900.00 a year in fuel costs

In addition to the DURAMILEAGE tuning we also Flow-Matched the injectors which helped balance out the engine and added to the over all mileage increase.


WHY YOU SHOULD HAVE DURAMILEAGE IN YOUR TRUCK:

#1 FUEL ECONOMY SAVINGS: Our customers consistently claim gains ranging from 15-25% (TYPICALLY 4-7 MILES PER GALLON) which saves them hundreds if not thousands of dollars a year. (Remember we saved approximately $1900 a year with our truck by changing the fuel mileage from 14 to 20)

Towing Performance: Having just the right horsepower and torque in the "towing zone" of your RPM range makes for a pretty sweet experience when pulling steep grades. Your transmission stays in higher gears which allows for higher hill pulling speeds and better economy.

Proven Results: It works!!! After programming hundreds of trucks we can conclude there is absolutely no available method that is as superior. Most of our tried and true calibrations were first developed on a Dyno and fine tuned in real world situations.

Warranty Friendly: Since we utilize the entire "stock" computer file GM technicians have no way of detecting any changes made to the ECM fuel maps. We have actually received several phone calls from technicians wanting to know what we had done because the customer told them about us and they could see the results but not find the reason for it. (reading the various diesel forums we know warranty issues are a great concern)

Adjust Factory Functions: We can adjust factory limitations such as the rev limiter and Speed Limiter and Tire Size can be recalibrated if you have installed larger/smaller tires.

OWNING DURAMILEAGE IS SIMPLE:

> OPTION #1 Customer's ECM: (FASTEST) Ship us your truck's ECM and we will remap the fuel tables with our tried and true fuel maps that meet your driving needs. (turn around time can be 48 hours if you "Overnight" your ECM) Installation and deinstallation of the ECM is extremely quick (5-10 minutes) and simple. The ECM is attached to the lower portion of the driver’s side battery and easy to access. (see diagram

> Option #2 Downloader: We can ship you a tune specifically designed for your truck on a Flash-Downloader. (may take up to 3-weeks depending on availability)

> Option #3 PRE-TUNED ECM: Best method for warranty concious truck owners. This is a Second ECM calibrated with the tried and true DURAMILEAGE fuel maps programmed with your trucks VIN# and Tire Size.
(this is a Great Option if you are really busy and can not afford to have you truck down for 3-4 days)
