Dear LMM Duramax Owner,
We want you to feel confident purchasing our Duramileage Custom Tuning. We have spent the past 8 years perfecting our mileage tunes.
We have installed our Duramileage tuning in roughly 10,000 Duramax diesels.
Although 100% of our customers have not seen mileage gains... we have testimony of many who have seen up to 4-7 MPG increases.
Less than 5% of our customers have returned their product for a refund.
The #1 Selling Duramileage tuning option is our EZTuner. It contains our best "tried and true" mileage tunes and it also allows your to adjust tire size, remove your speed governor, and check and clear diagnostic trouble codes.
READ THE TESTIMONIES... THIS PRODUCT WORKS!
We suggest you use the 60ECON power setting for the 2007.5-20010 to achieve "the best" gains.
We have TWO Options for the LMM:
* EZTuner - Preloaded with several "Tried n True" Mileage/Towing Tunes
* Customer's ECM - Least cost option
With the Customer ECMs we use the tuning file that "thousands" of our customers report the best mileage gains with.
#1 LMM Question: Do you have to remove the Particulate Filter (DPF) to see fuel mileage gains?
ANSWER: NO... installing our 60ECON tune from the EZtuner will improve your mileage 4-7 MPG. This is the program we install in Pre-Tune ECMs also. IT IS AGAINST FEDERAL AND CARB REGULATIONS TO OPERATE YOUR VEHICLE WITH THE DPF (particulate filter) REMOVED ON FEDERAL AND STATE HIGHWAYS
EXHAUST & AIR INTAKES
Daily we are asked if aftermarket air intakes and exhaust help increase mileage. After talking to roughly 100 Diesel owners a week for 10 years... we still don't have a solid answer.
It seems that it is about 50/50 on results. One diesel owner will tell us YES... and the next diesel owner will tell us no.
For those diesel owner who wish to purchase an aftermarket air intake or exhaust we do offer what we feel is the best product on the market for the best price.
Click on the "Exhaust and Air Intake" link above to purchase.
If your Duramax's fuel injection system (injectors, pumps, etc) does not seem to be running as it should we recommend you call Barry Sadler at 1-208-512-7608. Barry is one of the best mechanics we know that can "trouble shoot" INJECTOR issues over the phone. Barry has set several world land-speed records in diesel trucks!
