Built for L5P owners who want custom tuning and core EGR hardware without being forced into a full exhaust package they may not need.
This package combines custom HP Tuners tuning with the EGR hardware setup for your 2017–2023 Duramax L5P, giving you a cleaner starting point for a serious off-road build. It keeps the main hardware package together, while letting you choose your pipe add-ons separately so you are not paying for extra exhaust parts by default.
The tune is built around your truck’s current setup and goals, not pulled off a shelf and tossed over the fence. Whether you are after a straightforward single tune or want to step up to Shift On The Fly, this package gives you the core setup without overcomplicating the buying process.
