FOUR REASONS TO OWN DURAMILEAGE CUSTOM MILEAGE TUNES
(the majority of our tunes were built with EFI Live)

FUEL ECONOMY SAVINGS: Some of our customers have testified to us of mileage gains ranging up to 4-7 MILES PER GALLON running unloaded. If you can increase your mileage you can save money on fuel.

TOWING PERFORMANCE: Some customers have reported up to a 20% mileage increase while towing. Also... having the right horsepower and torque in the "driving zone" of your RPM range makes for a pretty sweet experience when pulling steep grades. Your transmission stays in higher gears which allows for faster hill pulling speeds and better economy.

PROVEN RESULTS: It works!!! After programming thousands of Duramax diesels we can conclude Duramileage tuning works from all the feedback we have received from satisfied customers.

PEACE OF MIND: Our Economy tunes are mild and we have not had much negative feedback on transmission issues or high EGTs beyond safe operating temperatures.

THE FUEL MILEAGE ISSUE IS EMISSIONS DE-TUNING!
(*Please Note we do advocate the removal of emissions equipment on any vehicle!)

You may feel like your Duramax has plenty of power but the fact is Emission Standards have forced de-tuning of the low-end power curve of your diesel. This de-tuning over the past 10 years has caused diesels to drop from 20-25 MPG down to NEW trucks averaging 14-16 MPG.

The only way to get back the loss in fuel mileage is to increase the low-end power curve of your diesel.

YOU MUST INCREASE LOW-END TORQUE RISE!

To restore mileage you must change the "peak efficiency" of the motor to match your driving/towing RPM speed. This added low-end torque rise significantly improves fuel economy because the engine now does more work with less effort.

After increasing low-end torque many of our diesel customers tell us they were once getting 13-16 MPG and are now seeing up to 18-23 MPG. Plus they now 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!

THE SOLUTION IS EASY TO INSTALL!

Yes, it is true there truly is a proven SAFE way to increase your Duramax's fuel economy and towing ability without the hype, hazards, and hidden costs associated with most diesel chips and delete kits.

The fact is, over 12,000 hard-working Duramax diesel truck owners just like you are now experiencing incredible money-saving fuel mileage gains and more towing power because they upgraded their trucks with the easy to install EZTuner Custom Mileage Tunes .

So effective are the EZTuner mileage tunes at giving you both optimal fuel mileage and power gains, that it makes other performance products nearly obsolete with its 30 Day Satisfaction Guarantee.

The EZTuner was specifically developed for the Duramax truck owner who is frustrated with their fuel mileage, but donu2019t want to void their warranty reprogramming the factory computer or installing expensive delete kits.

The price is affordable for almost any budget and easy enough for anyone to install. If you are frustrated with less than optimal fuel mileage you now have a solution!

If you are daily driving or going cross country, 100 EXTRA miles per tank of fuel adds up fast when it comes to money in your wallet. Stopping less to fuel up makes traveling more enjoyable and more affordable when you are saving $20 for every $100 in fuel. (up to 20% MPG increase)

WHAT MAKES THE EZTUNER DIFFERENT?

The main difference between the EZTuner and most diesel performance products is the manipulation of injector fuel volume. Chips/programmers increase injector pulse width which adds fuel to the engine to increase power... the EZTuner finely tunes the pulse width to bring the engine up to its peak efficiency and keep it there without over-fueling the engine.

Excessive injector pulse width modification adds to much fuel which causes the engines to run rich (smoke/heat)... whereas the EZTuner's finely tuned modifications cause the engine to run more efficiently due to improved combustion. These fine-tuned modifications do add slightly more fuel under throttle but the additional combustion performance offsets any negatives.

The Number One reason customers install the EZTuner is for fuel savings, but having up to an additional 100 horsepower (140 ft/lbs torque) makes for a more responsive truck when towing heavy loads. You can now get heavy loads moving faster and keep them moving faster on steep grades with less downshifting. (faster turbo spool gets you through intersections quicker)

The EZTuner is a diesel performance product suitable for today's hi-tech diesel engines. You simply plug the EZTuner into the OBD2 data port and follow the screen prompts. Your mileage tunes are installed in just a few minutes.

EZTuner gives you proven results with the best of both worlds. You get incredible money-saving benefits of better fuel economy and an amazing engine performance increase and at the same time! Instead of being frustrated with your diesel, simply upgrade it with an EZTuner and get the fuel mileage increase and first-class towing power gains you deserve.

BOTTOM LINE:

You can't just wish for better mileage and do nothing!

Act now and Order an EZTuner for your diesel!

I guarantee you that nowhere else will you find what EZTuner custom mileage tunes can do for you when it comes to both mileage and power improvements.

Not fully satisfied

I’m not sure if Diesel Domination has done anything for my 2007 GMC 6.6, I bought this programmer for fuel improvement, and I’m getting 15 mpg and less, not what I was expecting, not sure I’m getting what I thought I was paying for.

My 2007 GMC Duramax

I installed the recommended program for optimum towing and gas mileage. I really like the dramatic improved response from a full stop condition. And while I have not yet hooked up my 5th wheel trailer, I fully expect the improved performance to translate over. I should also share that I am averaging 21.5 mpg on the road and 19.8 overall mpg. I do have an aux. 45 gal fuel tank that currently has Lucas injector additive in the fuel. Once I empty the six tank I plan to stop the injector additive so I can evaluate the mileage without a fuel additive.

Delayed install

My truck set a P0087 just before I received the tuner. Early diagnostics indicate injectors needed. I'm undecided whether to install the tuner to see if it helps or let the dealer finish diagnostics with the stock software.

Outdated or incorrect programmer

I finally had the time to install this. The programmer I received does not match the instructions nor the video. There is no Yes or No buttons, but instead Off and On buttons. After some trial a error I figured out that Off = Yes and On = No (!??). I was not able to adjust the tire size. The +/- buttons did not work and everything I tried just put me back to the beginning. The manual looks like it was just printed off a home printer and contains confusing information. The information on the video about the different power levels are not explained in the manual. I am not sure how this programmer got through your quality assurance process?

So far pretty good.

Averaging 4MPG better while towing 11k 5th wheel. Was never lacking power before but now it’s even better. I’ve seen as much as 9 MPG improvement while empty.
