Duramax L5P Performance Module 2017-2022
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, MAP 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.

Why a Dr. Performance module?
You got a new diesel truck advertised with supercar levels of torque and power. But does it really feel like it? You step on the pedal, but your truck decides to wait a few seconds before giving you what you asked for. You know what I’m talking about – turbo lag. And those few seconds feel like an eternity when you have a fifth wheel behind you and you’re trying to pass the schmuck who has been going 8 under the speed limit since you got back on the highway (after your wife and kids conveniently needed their 3rd bathroom break in the last hour).
Okay, maybe that isn’t your exact situation. Or maybe it hit a little too close to home. Regardless, I think we can all agree that we aren’t getting all that power we paid for. I’ve got some good news for you. That power you were promised is indeed there. You just have to unlock it.
And no – I’m not about to tell you to delete your truck or download a tune that will void your warranty and put excessive strain on your nice new truck. I’ve got something better. The Dr. Performance Pro Performance Module.

Q: Will it damage my transmission?
A: No. Dr. Performance Pro Performance Modules will actually give you a smoother and cleaner running powertrain, and in many cases will improve transmission performance due to not needing to shift down as often. Dr. Performance Modules do not over-ride safety parameters.
Q: Do I need gauges or any other modifications?
A: Nope! Unlike some modifications that require monitoring devices, the Dr. Performance module works within your trucks factory safety parameters. Our module is designed to work on completely stock trucks.
Q: How hard is it to install?
A: Not hard at all! Most our modules can be installed in 20 minutes or less with little to no tools required. Our modules use factory OEM plugs and plug inline with the fuel pressure sensor and on some models the boost sensor as well. Installation varies from truck to truck, but all can be installed yourself with little to no mechanical knowledge. All modules come included with detailed installation instructions with pictures. We also have all installation instructions here. We are available 24/7 via phone if you run into any issues! (800) 406-5257
Q: Is it safe to tow with?
A: Absolutely! If anything, one might argue that it’s safer to tow with our module. With our module you can tow as you normally would. Make sure to use your trucks tow/haul mode when in tow!
Q: How much power will I actually gain?
A: On average we see gains of 30-90 hp to the wheels and up to 120 lb-ft of torque. Keep in mind these modules provide functional low to midrange power in the daily driving and towing RPM range. A dyno measures power at wide open throttle – it doesn’t measure daily driving improvements like rolling into the throttle and holding gears better. These modules make a difference in the 99% of driving situations when you aren’t at wide open throttle.
Q: Why should I get a module instead of a tuner?A: Different strokes for different folks! If you are looking to turn your truck into race car, maybe a tuner is better suited for. Tuners focus on top end power. Our module focuses on the low to mid-range RPMs where most all of your driving is spent. Tuners flash your ECM, void your warranty, and produce additional wear and tear on your engine. The Dr. Performance Module is a safe way to gain power all without sacrificing your warranty.
