GMC Sierra 2500 HD Tuner - Banks Power - Derringer - `17-`19. A plug-in performance module engineered for 2017–2019 6.6L Duramax L5P trucks that increases torque and horsepower across the rpm range while preserving factory controls and drivability.

The Banks Derringer is a calibrated, in-line tuner that uses multiple engine inputs and the vehicle OBD-II bus to adjust power in real time. It offers six user-selectable power levels (adjustable on-the-fly with a Banks iDash) to suit towing, work, or performance use. ActiveSafety monitoring and TransCommand transmission protection help the Derringer limit risk by reducing or bypassing power if abnormal conditions or knock are detected. Installation is straightforward plug-and-play and the unit is removable for dealer service. Note: iDash is required for level switching and some display functions; iDash not included.
