Banks Power Duramax Derringer Tuner Gen 2

The Banks Power Duramax Derringer Tuner Gen 2 is a game-changer for 2020-2023 GM 2500 6.6L L5P Duramax owners looking to unlock the true potential of their vehicles. With six years of engine and chassis dyno experience, this tuner is meticulously calibrated to provide exceptional torque and power gains across the entire operating rpm range. The Derringer Tuner is designed to work seamlessly with your engine's ECU, using multiple data inputs for real-time optimization. This ensures that your vehicle not only performs better but also remains safe and reliable.

Unmatched Performance and Control

The Derringer Tuner offers three switched settings: Stock, Plus, and Sport. The Sport setting, featuring the innovative Afterburner technology, delivers the best-in-class performance, reducing your 0-60 time by a full second and your 0-100 time by an impressive 4 seconds. The Plus setting is perfect for work use, providing a great mid-range feel that enhances your on-ramp merging speeds and passing times when pulling a trailer. This versatile tuner adapts to your driving style, ensuring that you get the most out of your vehicle at all times.

Advanced Technology and Safety

The Derringer Tuner's electronics are molded into a waterproof connector, making it easy to conceal and integrate with other devices like the iDash 1.8 Super Gauge/Control Center. It connects in line with key sensors such as FRP, TMAP, EGT, and OBDII diagnostic bus connector, ensuring seamless communication. The CAN transceiver chip allows for advanced communication with OBD or B-Bus, while the coolant temp watchdog prevents power addition when the engine is too cold or overheated. This ensures maximum safe power at all times. With the exclusive Adaptive Tuning methodology, the Derringer Tuner guarantees a smooth and safe driving experience, making it a must-have for any Duramax owner.
