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 Pro Performance Module was specifically developed for the diesel 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 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.

2019 Colorado ZR2 diesel

Have put about 2,300 miles on truck driving across country using Pos 3 (+60hp). Love the extra power and torque, but haven’t really seen any improvement in mileage. Yes, if you believe the computer I’m getting better mileage with more power, but by actually figuring out the mileage I have found my computer is off about 10% because the computer is using a false pressure indication in its calculations so it is spraying more fuel then it thinks. Nothing is free so I am overall happy with it and will try Pos 2 to see how that does with fuel and power.

A safe program!

Very little performance increase. Wonder if I didn't install it correctly! Fuel mileage had very little increased if noticeable. Easy to install, with plug-n-play installation. Maybe the dial isn't set on the settings I was thinking, will double check it!

Duramax 2.8LPro performance

My experience was pretty simple I received it unpacked it read directions. On my Colorado I did have one question about the wiring harness connectors on fuel rail there’s 2 connectors and I wasn’t sure which one to remove so I called Diesel Domination and they told me which one it was,I made all the connections started the engine waited a couple of minutes pulled truck on to the street and put the pedal to the metal !!! The trucks performance much better than the stock set up. I do a lot of Highway driving the performance is so much better I would recommend this Product if you want better performance and mileage M Provo.

For the money not bad!

Surprisingly easy to install, other then getting the GM plug to unplug in the fuel rail. Throttle response is much better then factory but I don't think it's getting 60 extra points in the #4 tune. If I gain mph and better pulling power it will be worth the money!
