Derringer® High Output

The Banks Derringer High Output is designed for those who work their 2024-2026 Duramax 6.6L trucks. The system provides a massive increase in torque across the working RPM range of the engine. Merging, passing and uphill climbs while towing are easier than ever. Choose from 6 power levels as you drive, including fuel economy calibrations, work, and max power. Derringer communicates with the truck's ECM to adjust the tune in real-time, even compensating for altitude. ActiveSafety circuitry protects the engine and transmission. Derringer is controlled by the all-new iDash Pro Powertrain Information Center with Bluetooth mobile app. Best of all, it's warranty friendly. After removal, there's no trace left behind. 50-state emissions compliant.
