What is the Dr. Performance Pro Performance Module?

Simply put, the Dr. Performance Pro Performance Module is a minicomputer that plugs in under the hood and optimizes fuel pressure to create a finer flume of fuel which results in a more complete fuel burn. This results in better combustion quality, efficiency, and power output. That means more torque when you need it, a much smoother power band, and significantly increased responsiveness.

Most daily driving in a diesel is spent in the lower RPM range. This is exactly where our module increases power and gives you much more predictable performance through the bottom end of your gears.

Unlike a tuner which downloads over your trucks ECM and overrides your trucks safety parameters, our module plugs in-between your fuel pressure sensor and your ECM. That means your truck never operates outside of its safety parameters and you get to keep your warranty! For a detailed write-up on the difference between tuners and our module, check out a blog we wrote here.

With this module you can hold higher gears and keep your RPMs down. That usually means improved MPG. Mileage is impossible to guarantee with any modifications, but the majority of our customers see a nice bump in fuel economy on top of the improved driving experience. Please consider improved mileage as a potential bonus to the power gains.

The Dr. Performance Pro Performance Module comes included with a 4-position selectable switch (stock, low, medium, and high). We recommend starting off with the switch in the medium position for two full tanks of fuel. After that, play around with the different settings and see which one suits you best!

If you are looking for a safe, cost-effective, and easily installed modification for your diesel truck to get some serious results, then the Dr. Performance Pro Performance Module is the product for you. Get the power you really paid for today.
