Chevrolet Silverado 3500 Tuner - Banks Power - Derringer - `17-`19 is a plug-and-play performance tuner engineered for 2017–2019 Silverado 3500HD 6.6L Duramax (L5P). It provides selectable power levels and real-time calibration to improve torque and drivability for towing and daily driving.

The Derringer uses multiple vehicle inputs—throttle position, rpm, vehicle speed, AFR, knock, coolant temp and EGT—and connects to the OBD-II bus to actively optimize engine calibrations. It delivers measurable torque and horsepower gains throughout the rpm range without reflashing the factory ECM, and includes safety features that monitor system health and automatically revert to stock if an issue is detected. Designed to integrate with Banks iDash devices (iDash required, not included), Derringer gives on-the-fly control and diagnostics while supporting DPF and DEF status displays and commanded regen via iDash on compatible years.
