Stock diesel engine's warranty-friendly best friend.

Stock vs module

Keep the factory settings. Change how they respond.

Factory engine detuning robs you of driving-zone HP, mileage, and throttle response. Our warranty-friendly performance module targets the driving-zone to deliver accessible power, torque and mileage gains, while the ECM stays untouched.

What stock diesel owners are saying

Hood work, then highway

I put it on my 2019 L5P in the driveway after work. Connectors clicked like factory. Next morning the throttle actually showed up when I merged. Still stock under the hood besides the module. Took me longer to take it out of the box than to install it. I put it on my 2019 L5P in the driveway after work. Connectors clicked like factory.

Dead pedal is gone

Had the truck 3 years and hated that empty first inch of pedal and bad mileage. After a week with this, city driving feels normal again. Turbo really kicks in sooner, and i'm up 3.5 mpg's. Wish i did it a long time ago. Had the truck 3 years and hated that empty first inch of pedal and bad mileage. After a week with this, city driving feels normal again.

Tow days feel calmer

I haul a small trailer on weekends. Used to wait on the turbo, then it would dump in. Now the truck fills in earlier so I am not stabbing it. Mileage on mixed weeks looks better than last summer. Not magic, just less lag and less waiting. I haul a small trailer on weekends. Used to wait on the turbo, then it would dump in. Now the truck fills in earlier so I am not stabbing it.

Left the ECM alone

I wanted more response without flashing anything. Installed it under the hood, drove it to work, and the truck still feels like my Duramax. Just sharper when I ask. That was the whole point for me.

Daily commute, less lag

On-ramp is where I notice it. Pedal used to sit there, then the turbo would catch. Now it comes on when I need it. Simple install, no extra gauges, and I have not touched intake or exhaust. Four months in and I still look forward to the drive home. On-ramp is where I notice it. Pedal used to sit there, then the turbo would catch. Now it comes on when I need it.
