Do you need and 'affordable' and 'easy' solution to increase your Duramax fuel economy?

Dear Duramax Diesel Owner,

I understand your frustration with owning an expensive diesel and yet like most diesel owners you are getting less than optimal Duramax fuel mileage.

Poor fuel mileage and high diesel prices affect our wallets... especially the folks who make a living with their trucks because every fill-up cuts into your bottom line. In a struggling economy high fuel prices and low fuel mileage is something we should not have to deal with.


When light-duty diesel pickups gained popularity in the 1990's is was common to see 25 and even sometimes 30 MPG. Today these new trucks are averaging less than 15 MPG. The reason for this drop in mileage has to do with the de-tuning of your engine.

You may feel like your truck has plenty of power but the fact is the manufactures are now forced to detune the low-end RPM power curve in-order to meet current emission standards. While this a good thing for our environment the de-tuning of the low-end power curve and the added emissions devices restrict the motor and lower fuel economy.


I know that it is possible to reach 30 MPG in a diesel pickup I also know the solution is very expensive and requires a lot of modifications. What I have found as the in-expensive solution to increase the mileage 3-5 MPG is to increase the lower-end torque Diesels are a workhorse engine and are designed for High-Torque output at low-RPM. Today you can find dozens of websites making fuel mileage claims because of the high demand for better fuel mileage.

The problem is none of these companies products can consistently put their money where their mouth is. I know this because we talk to dozens of Duramax truck owners every week who have installed these products and tell us the results. These products are not solving the problem of the de-tuned low-end power curve of the engine!


Several years ago I discovered that the simplest way to squeeze more miles per gallon on the Duramax was to re-calibrate the trucks fuel maps and "increase the engine's low-end torque rise". Tuning the Duramax motor with custom fuel and timing maps I am able to adjust the engine's low-end power curve giving it a faster torque rise and some of our customers are reporting to us they are seeing mileage gains of 4-7 MPG running empty and 20% increase while towing. (see Testimonies)

Remapping the engines "fuel and timing tables" changes the "peak efficiency" of the motor to match your driving/towing RPM speed. This low-end torque rise significantly improves fuel economy because the engine now does more work with less effort.

Some of our Duramax customers tell us they were once getting 13-15 MPG and are now seeing up to 18-23 MPG and they get over 100 more miles out of every tank of fuel. Imagine how much our customers are saving in fuel costs when they get 100 more miles out of every tank of fuel! EZTuner is the Duramax programmer / tuner you are looking for.
