We here at Diesel Domination have been selling "original" Dr Performance diesel modules since 2003 and truly believe they are the absolute best product on the market for "Working-Class/ Daily Drivers".

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

Ten’s 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 don’t 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 mileage… 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 manufactures to de-tune your truck below 2000 RPM. This de-tuning has caused diesels to loose several mileage per gallon 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 to 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 “plug and play” diesel performance product suitable for today’s 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 engine’s fuel delivery with precise electronic control of injection pressure.

Pro Performance Module gives you proven results with the “best of both worlds”. 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.

Arrived promptly although after installation I have not noticed much difference. 700 mile trip with my RV , mileage is still 10.1 response is the same still unsure if it was a smart purchase, hope 180 day trial is still valid. It’s still installed and I have more miles to go, so will know in another week or so how the mileage is.

Installed and noticed fuel mileage go from 13-16 to 16-22 mpg calculated. Much better throttle. Towing 32’ toy hauler 7500 lbs get up and go is awesome. Fuel went fro 9.5-10 to 11.5-12 at 65- 70 mph.
Totally satisfied and would recommend. Contacted technician once, friendly and helpful.

Contacted Power-Up Diesel to discuss my needs for my GMC Denali HD to ensure the module would provide the extra power and mileage I was wanting. Technician was friendly, explained how the module worked and ease of installation.

Once module was installed I quickly realized the change in power and the increase in fuel mileage (3-4 mpg gain), thanks Power-Up Diesel!
