Banks Power Derringer Tuner for GM 2500/3500 6.6L Duramax

The Banks Power Derringer Tuner is a game-changer for GM 2500 and 3500 6.6L L5P Duramax owners, offering an unparalleled level of performance enhancement. With over six years of engine and chassis dyno experience, this tuner is designed to provide substantial torque and power gains across the entire operating rpm range. The Derringer Tuner is calibrated to use multiple data inputs, mirroring your engine's ECU, ensuring real-time, active, and safe optimization of calibrations. This advanced technology sets it apart from competitors, delivering a seamless and powerful driving experience.

Unmatched Performance with Three Settings

The Derringer Tuner features three switched settings to cater to different driving needs: Stock, Plus, and Sport. The Sport setting, with its Afterburner feature, provides the ultimate performance boost, similar to the military Combat Power settings. This results in a dramatic improvement in acceleration times, cutting 0-60 mph to just one second, 0-80 mph to 2.1 seconds, and 0-100 mph to an impressive 4 seconds. The Plus setting, ideal for work use, offers a great mid-range feel, significantly enhancing on-ramp merging speeds and passing times when towing or carrying heavy loads.

Advanced Connectivity and Safety Features

The Derringer Tuner is designed with advanced connectivity in mind, featuring a waterproof connector that easily conceals and communicates using the B-Bus with other devices like the iDash 1.8 Super Gauge/Control Center. It connects in line with key sensors, including FRP, TMAP, EGT, and OBDII diagnostic bus connector, ensuring seamless integration and data transfer. The CAN transceiver chip enables communication with OBD or B-Bus, allowing for real-time data analysis. Safety is paramount, with the Derringer's special coolant temp watchdog preventing power addition when the engine is too cold or overheated. This ensures maximum safe power, all while benefiting from Banks' exclusive Adaptive Tuning methodology.
