Banks Power Derringer Tuner Gen 2 with 1.8in iDash for 2017-2019 GM 2500/3500 HD (6.6L)

Fits 2017-2019 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD (6.6L L5P Duramax).

The Banks Power Derringer Tuner Gen 2 is a dyno-calibrated performance upgrade designed to provide immediate torque and horsepower gains throughout the entire RPM range. By interfacing with the vehicle's OBD-II diagnostic bus, the Derringer monitors multiple data inputs including throttle position, RPM, AFR, and EGT to optimize calibrations in real-time. This kit includes the 1.8-inch iDash for on-the-fly adjustment across six power levels, ranging from fuel-efficient work settings to maximum performance.

Safety is prioritized through the integrated ActiveSafety health monitoring circuitry, which samples engine data 100 times per second. If the system detects an issue or unsafe operating temperatures (too cold or overheated), it automatically bypasses the tuner to protect the engine and seamlessly returns the vehicle to stock power levels. Installation is a straightforward plug-and-play process that connects in-line with factory sensors for easy removal before dealer service.
