Don't be frustrated with your mileage... improve it!

Since 2003 we here at Diesel Domination Inc have focused solely on upgrading "Working-Class Daily Drivers". We truly believe the "original" Dr. Performance Pro Diesel Modules are the Safest, most Warranty Friendly diesel performance products on the market.

The Pro Performance Module is the proven SAFE and WARRANTY FRIENDLY way to increase your dieselu2019s fuel economy and towing ability without the hype, hazards, and hidden costs associated with most diesel chips and delete kits.

Tenu2019s of thousands of hard-working 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 Pro Performance Module.

So effective is the Pro Performance Module at giving you both optimal fuel mileage and power gains, that it makes other diesel performance products nearly obsolete.

The price is affordable for most any budget and easy enough for anyone to install. If you are frustrated with less than optimal fuel mileageu2026 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)


You feel like your truck has plenty of power but the fact is Emission Standards have forced manufacturers to de-tune your truck below 2000 RPM. This de-tuning has caused diesels to lose mileage over the years.

To restore your truck's fuel mileage, you must change the "peak efficiency" of the motor to match your driving/towing RPM speed. Increase the low-end torque rise of your motor 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 their trucks that were once getting 13-16 MPG and are now seeing up to 18-23 MPG.


The main difference between the Pro Performance Module and most electronic diesel performance products is the manipulation of fuel pressure vs fuel volume. Most chips/programmers change injector pulse width which adds for fuel to the engine... the Module changes fuel pressure which enhances the injector plume and increases the fuel atomization.

Excessive injector pulse width modification adds too much fuel volume and can cause the engine to run rich (smoke/heat)... whereas pressure/plume modification causes the engine to run more efficient due to improved fuel atomization. Pressure modification does add slightly more fuel under throttle but the additional combustion performance offsets any negatives.

The Number One reason customers install the Performance Module is for fuel savings but having up to an additional 90 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 Pro Performance Module is an easy to install u201cplug and playu201d diesel performance product suitable for todayu2019s hi-tech diesel engines. Engineered with advanced digital-microprocessor technology, the Module simply plugs into your factory wire-harness with OEM style plugs and helps manages your engineu2019s fuel delivery with precise electronic control of injection pressure.

Pro Performance Module gives you proven results with the u201cbest of both worldsu201d. 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 a Pro Performance Module and get the fuel mileage increase and first-class towing power gains you deserve.


You can't just wish for better mileage and do nothing... You must change your diesel's "peak efficiency" to increase your fuel mileage.

Add the Pro Performance Module to your Cart "RIGHT NOW" and start experiencing for yourself what thousands of hard-working Powerstroke, Cummins, and Duramax diesel owners are already enjoying.

2017 Ram 2500

Not super difficult to install video helped a lot. Used a few more zip ties than provided. Drilled hole in lower dash to install setting. Ran wires into cab. I’m getting 2.5 miles more per gallon after about 4 months of use. Like the increased power and acceleration. Also easier to pull hills with trailer.

Conservatively Optimistic

With the stay at home regulations in effect for 4 weeks now. I wasn't able to get any tech support on how to locate the harness on my 2019 Dodge Ram. I finally did locate them and was able to install the module (with great difficulty I might add). I guess its installed properly as no warning indicators came on and the truck seems to run normal. Its been over 4 weeks since I got it and after 3 separate attempts to install it, I just now had success.

broke my truck

I watched the video about the better fuel mileage on my cummins engine, the video promised a substantial fuel mileage increase or 110% of your money back im excited because I know how to do math and can see the savings --so I call in tell them I have a 2020 dodge with a cummins engine do they have a controller for it, the sales man asks me to hold he needs to talk with Steve the owner back on the phone tells me yes I pay for it and they ship the module to me. I had run two tanks of fuel thru my truck to get a mileage baseline I then installed the module within a half tank of fuel I get a DPF filter plugged see dealer we are talking about a new truck with less than 1000 miles on it, I immediately remove the module take my truck in which they kept 3 days to clean out the DPF I call Diesel Domination tell them what happened and to refund my money they inturn refer me to Travis at DR Diesel and he informs me they do not have a module for a 2020 and wont for another 6 weeks or so,i then call Diesel Domination back and asked for the RMA and my money. They did send me an RMA and I did return the product but to this day have not seen a refund that was 10 days ago the signed for the package as it was shipped UPS so I could track. Long story short beware and hopefully all this turns out
