Overview

The Banks Power Derringer Tuner is an advanced inline tuner for 2017-2019 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks equipped with the 6.6L Duramax L5P engine. This tuner interfaces with the vehicle's ECM via OBD-II and features AutoRate technology to adjust tunes in real-time using vehicle data.

It offers six power levels, adjustable on-the-fly with the included iDash DataMonster, with each level adding approximately 12 hp. The system includes ActiveSafety to protect the engine and powertrain, and TransCommand to safeguard the transmission. The Derringer connects inline with engine sensors and also communicates through the OBD-II port, providing safety features that bypass the module and return the truck to stock power if an issue is detected. It also monitors coolant temperature and adjusts power if knock occurs due to fuel quality.

Part #: 66793

Results in torque and power gains across the full operating rpm range, starting right off idle and marching to the shift point in each gear. Derringer is dyno calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFR, knock, coolant temperature, and EGT, just like your engine's ECM. It actively and safely optimizes calibrations in real-time thanks to its OBD-II connectivity. No competitive tuner does that.Derringer has 6 levels, adjustable on-the-fly using the iDash. Level 6 produces best-in-class performance. Level 3 is designed for work use and has a great mid-range feel. When running Level 3 with a loaded truck and/or pulling a trailer, your on-ramp merging speeds and passing times are greatly improved.The electronics are enclosed in a compact housing which is easily concealed and communicates with other Banks devices such as our iDash DataMonster, iDash SuperGauge, and PedalMonster throttle booster. The Derringer connects in line with your truck's engine sensors. But unlike other tuners, it also connects to the vehicle's OBD-II diagnostic bus.ActiveSafety health monitoring circuitry keeps an eye on the vehicle and the module itself. It checks its health 100 times a second. If it detects an issue, the Derringer instantly bypasses itself, sets a device diagnostic code, and seamlessly returns the truck to stock power. Plus, Derringer's special coolant temp monitoring prevents power addition when the engine is too cold or overheated. The Derringer also auto-adjusts power if knock occurs due to bad fuel. Maximum safe power is all automatic with a Derringer you just choose your preferred power level and enjoy the ride.
