Steve,

Thanks for the ECM upgrade! I had just purchased this truck ( 2006 2500HD ) and was very disappointed with the mileage, at 15.1 per gallon. I had several people tell me to install a chip in this truck. I figured this was not the option for me as this is my first diesel truck. That's all I need is more controls and gauges to set and I wouldn't know where to set them anyway. So I opted to let you take care of it and the results are terrific. I took the truck to Nashville (from Kansas city area)  and averaged 22.8 per gallon and the horse power is more than I need pulling my 5th wheel camper. Thanks again it was well worth the money.

Steve,

I have a 2007 Classic GMC, lifted 3" ,285/70/17 tires, and a Buckstop bumper with a warn winch. The lift, tires, and bumper dropped my mileage from 17 to 15. When I put the ECM back in the truck I took a little test drive right off. The speedometer is right on now, and the truck goes faster than a guy should drive it since the speed limiter was adjusted as per my request. The power? Well I was impressed before but it exceeded that too. I'll get to the mileage in a bit but right now I'd like to put down what I saw change on my pyrometer and boost gauges. At stock I would get 20 psi pulling hard, if it shifted at the right timeit might bump 21 or 22psi. Now on hard acceleration, no load, the boost sits on 26 psi until I get moving. The pyrometer is in the exhaust manifold and running stock I could get 1350 degrees on a hard acceleration empty. And it got there fast. Now it runs much cooler. I tried to get it to 1350 and could only get to it about the time I felt like dropping the throttle because of speed. On normal runs small hills easily made 1000 to 1200 degrees where now 800 to 1000 degrees is normal.

Now to mileage. I've always had  very erratic mileage. My last average has been 14 to 15mpg. I filled up and run about 115 miles with the cruise on 65 mph. In that stretch I stayed the night at home and let it idle for 15 to 20 minutes then had a little town driving. The mileage figured 19.3 mpg. Then from that fuel up I made a 71 mile run at 76 mph on cruise that figured 17mpg. This was empty. Those are my first calculations.

I'm happy with what I have, a bit more driving will probably have more to say.

Steve,
The reprogrammed ECM was installed on a new 2007 2500HD Silverado extended cab 2WD. My best guess at the mpg prior to the installation was 16-17. I wasn't able to get an absolute reading before removing it (only had 180 miles). I immediately took a 3000 mile round trip from Missouri to Connecticut (following your guidelines of 65 mph in 5th) and averaged between 22mpg and 23mpg. I could not have asked for more.

I did find that, with a slight tail wind or drafting, I could do almost as well at 75 mph in 6th (2000 rpm).

Your product performs extremely well and I would recommend it to anyone.

Thanx - Ed Smith

January 2009 - Update

After countless times of filling the tank on my 06 Chevy Duramax, the frustration was to much and led me to Diesel Domination. I was getting 12 to 14 mpg normal driving and 6 to 9 mpg pulling. Steve did his magic and I am now seeing 16.5 to 20 mpg driving and 12 to 13 pulling! I am very happy with the results and will recommend this product to anyone. Thanks again Diesel Domination for saving me money!

 Steve,
 
    Hi, I installed the 100 horse duramilage tune with top speed limiter removed, tire size change and I am very satisfied.  The 100 horse tune really works well on daily driving and pulling my 30 ft fifth wheel camper.  The pulling power and throttle response is awesome. Before duramilage I was only getting 15mpg empty and 9mpg loaded.  Now I get 22mpg @ 70mph empty and 13mpg pulling 10,000 pounds.  Having this kind of power and fuel mileage makes it pleasure to drive my truck. My buddy and his dad have a duramax and they are putting duramilage on. I tell everyone I see that drives a duramax. Thanks for all your help. Duramileage is the only way to go!

 The pickup has been wroking great. I'm very happy and have been spreading the word to all my friends, hopefully they have contacted u. Here's my testimony with the 2006 LBZ.

Recently I stumbled upon an ad for the Duramilage product and I figured it was just another boastful ad that for a product that wouldn't return the results it garunteed.  I was very disapointed with my 06 chevy duramax. The milage was terrible, getting arould 13mpg empty and 8mpg pulling a trailer. I visited with Steve and he was confident he could help me gain the mileage I was thinking the Duramax should get. Instantly the results were great. I was up to 19mpg at normal driving speeds and even maintained 18mpg at 90 plus mph! Pulling a trailer, the mileage increased to 12 -13mpg and the power increase was very noticeable. I love the results and recommend this product to anyone who wants mileage gains!

Hello Steve, Odometer reading is 15186.

 

After spending thousands of $$ with no increase in fuel economy, I ran across your web site. I will now be keeping my 2007 Classic Duramax and driving it daily. I has sat for months because the best I could do was 15 mpg. After getting my computer back from you in less than a week, I have never been more pleased driving my truck. Yes, I get 7 mpg better with a combination freeway and town driving. Same driving habit and same destinations. I now get 22 mpg. You really need to go to Chevrolet and convert all there trucks, maybe they wouldn't be shutting down all the plants.

 

Thanks so much, my exhaust, cold air intake, and Banks set up where a huge waste of money. I will be sending you a few customers.

I have been using and evaluating DURAMILEAGE for more than 3 months now.  The bottom line is that it works as advertised (even better!) and Steve Shelly does what he says he will do.

Like many people I was looking for ways to increase my mileage and add a little power.  I found DURAMILEAGE when searching the internet.  At first, it seemed to be too good to be true and commentators on several web forums suggested the claims did not make sense.  Boy, were they ever wrong!  I think the diesel forums are great but you cannot always trust what contributors say particularly when they have not used the product.  After talking with Steve Shelly (the owner of DURAMILEAGE) I decided to take a chance. 

From the first installation I noticed was how quickly the transmission shifted thru the gears with more low-rpm torque.  I am now able to get up Snoqualmie Pass in whatever gear I want and maintain the speed limit if I choose.

There are several routine trips I take and I have documented mileage with and without my 11.5 ton fifth wheel trailer.  I was getting about 9.5 to 10.5 mpg towing and about 17-19 mpg unloaded on the freeway.  These were hand calculations after many fill ups.  (I’ve since documented for myself that while the DIC tends to suggest higher mpg’s it is consistent and useful to track changes made to the engine for comparisons.)  No matter whether using hand calculations or the DIC my mileage increased substantially with DURAMILEAGE.  I now get 12.5 to 14 mpg when towing (it depends on if I have filled my water tank or not).  And I get 22 to 24 mpg when unloaded and able to drive at a consistent highway speed. 

I did need to swap Steve’s ECM a couple of times with the stock one. [the customer had requested some changes which included shifting, fuel tank size, and service updates]  That really demonstrated how well the DURAMILEAGE tune works.  The mileage went way down with the stock tune and I found it frustrating to tow up Snoqualmie Pass once again.

The swaps were needed for Steve to make a couple of changes I wanted and to add the GMC updates for my model.  An unanticipated flash of the ECM required another fix from Steve.  He did the work without complaint and offered some advice along the way.  I’ve always found that you learn most about companies when things go wrong.  Steve really came through for me.

 So, would I do it again?  Absolutely!

Does his product work?  Yes, even better than I expected.

Can you trust Steve?  Most assuredly!
