Experience the ultimate Banks tuning package with the Banks Derringer High Output Tuner with iDash DataMonster. Designed exclusively for 2024-Current Chevrolet Silverado HD and GMC Sierra HD models powered by the 6.6L Duramax L5P, this intelligent tuning system safely delivers up to 86 additional rear-wheel horsepower and 178 lb-ft of rear-wheel torque, dramatically improving towing performance, acceleration and everyday drivability.

Unlike conventional tuning modules, Derringer communicates directly with the vehicle's OBD-II network, continuously monitoring engine operating conditions and dynamically adjusting power output in real time. This intelligent approach delivers strong, consistent performance without compromising engine durability or transmission longevity.

Included in the kit is the flagship Banks iDash DataMonster, giving you complete control over your vehicle's performance monitoring. In addition to displaying hundreds of live engine, transmission and drivetrain parameters, the DataMonster provides built-in data logging, record and playback functions, performance timers, 0-100 km/h and quarter-mile testing, configurable alarms and wireless Bluetooth firmware updates through the Banks Power App.

Banks' exclusive AutoRate® Dynamic Tuning constantly adjusts power based on engine load, altitude, coolant temperature and exhaust gas temperature to maximise safe performance. ActiveSafety® continuously monitors the engine up to 100 times per second, while TransCommand® intelligently manages torque delivery during Allison 10-speed gear changes to help protect the transmission under heavy towing or high-performance driving.

Installation is completely plug-and-play with no ECU reflash required, leaving no footprint in the factory ECM after removal while remaining 50-State emissions compliant.
