Take full control of your 6.6L Duramax with the Banks Derringer High Output Tuner with iDash Pro. Designed specifically for 2024-Current Chevrolet Silverado HD and GMC Sierra HD trucks, this intelligent performance module delivers substantial gains in horsepower and torque while preserving factory drivability, towing capability and long-term reliability. Unlike conventional plug-in tuners, Derringer communicates directly with the vehicle's ECM through the OBD-II network, continuously adjusting power based on real-time operating conditions.

The system provides up to 86 additional horsepower and 178 lb-ft of torque at the wheels, making towing, overtaking and steep climbs significantly easier. Drivers can select from six power levels on the fly using the included Banks iDash Pro Powertrain Information Center, allowing performance to be tailored for economy, towing or maximum power whenever required.

Banks' exclusive AutoRate® Dynamic Tuning constantly monitors vehicle diagnostics including engine load, altitude and operating temperatures, automatically adjusting the calibration to maximise safe performance. ActiveSafety® performs internal diagnostics up to 100 times per second to protect the engine, while TransCommand® manages torque delivery during gear changes to safeguard the Allison transmission under heavy loads.

Installation is completely reversible with no ECU reflash required, leaving no footprint in the factory ECM after removal. The included iDash Pro also displays live engine data, Derringer performance information and supports wireless Bluetooth updates via the Banks mobile app.
