While almost every chip,programmer, and tuner on the market changes the same base fuel maps (pulse and timing) it is how and where you adjust them that makes the difference. It is like no two bakers have the same recipe for making a chocolate cake.
While off the self chips and hand-held programmers do provide great power gains.. non will promise much of an increase in fuel mileage.
Most add too much fuel to the engine to reach their performance levels which can create higher exhaust gas temperatures and lower the fuel economy.
EZTuner fuel maps on the other hand not only give you usable Horsepower and Torque gains across the entire RPM range of your vehicle... your also get additional fuel mileage gains without high EGTs.
Our in-depth level of EZTuner tuning allows us to precisely calibrate dozens of engine parameter on your ECM for optimal performance. It is the difference between using a sledge hammer versus a surgeons scalpel to custom tune precisely to the customers needs.
TOP BENEFITS OF EZTUNER CUSTOM MILEAGE TUNING
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 increases 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.
With EZTuner Custom tuning you are not buying a one size fits all product... you are buying potentially money saving fuel mileage with the added benefit of increased towing performance.

RECENT TESTIMONY: Ron & Steve I would like to say thank you for a great tune (70Econ on EZTuner) on my 2006 Silverado ECM. It's been a while since i had it done but haven't had a chance to really check it out until just lately. I just finished a 1000 mile trip and was very happy with the results. I got in excess of five more miles to a gallon average on my trip, what a surprise. I had been getting four more miles per gallon around town so i was sure hiway miles would be better but it was great. The extra power was just a bonus. Thanks allot Guys / Sincerely Ray - California
