Boost Bros Performance - 6.6L L5P Duramax Build Your Own Kit (2017-2026)
Product Details
Take full control of your build with our Build Your Own Kit for the 6.6L L5P Duramax—designed for guys who want it done their way, not boxed into a pre-made package.
This isn’t a one-size-fits-all setup. Whether you’re building a clean daily, a tow rig with more authority, or a full-on performance truck, this kit gives you the flexibility to choose exactly what your truck needs—nothing more, nothing less.
Start with the essentials and build from there. Select from EGR upgrade kits, full exhaust systems, and high-flow downpipes to improve reliability, airflow, and overall efficiency. Then dial in the performance side with your choice of tuning devices, HP Tuners credits, and proven AMDP custom tune files built specifically for the L5P platform.
Every component is carefully selected to ensure compatibility, performance, and ease of installation—so you can build with confidence knowing everything works together seamlessly.
No guesswork. No wasted money. Just the exact setup you want.
Whether you're chasing horsepower, drivability, or long-term reliability, our Build Your Own Kit puts you in the driver’s seat.
