2020–2023 Duramax 6.6L Derringer High Output Tuning Bundle: +117 HP & +225 LB-FT

The Banks Tuning Bundle for 2020-22 and 2023 Chevy/GMC Duramax 6.6L packages together the Derringer High Output tuner, the iDash Data Pro Powertrain Information Center with mobile app, and the PedalMonster throttle controller. The Derringer High Output delivers a massive +117 hp and +225 lb-ft across 6 on-the-fly power levels that you can adjust while driving. By communicating directly with the truck’s ECM via OBD-II, the tuner adjusts calibration in real time and automatically compensates for altitude changes, while patented ActiveSafety circuitry safeguards both the engine and transmission. Meanwhile, PedalMonster sharpens acceleration and throttle response using 150 selectable throttle contours with Tip-In Control. Both modules are managed directly through the Banks iDash Data Pro Powertrain Information Center, the industry’s most advanced automotive evaluation and monitoring gauge. Regularly valued at $1,797, the complete Duramax Tuning Bundle launched at a special introductory price of $1,299.

How Derringer High Output Protects Your Duramax Powertrain

The Derringer High Output outpaces competing tuners like the Edge Pulsar by over half a truck length to 60 mph. At peak load, it runs 10 percent cooler exhaust gas temperatures while delivering 6 percent better fuel economy. Patented AutoRate dynamic calibration reads OBD-II data to modulate fueling based on barometric altitude and coolant temperature.

During heavy towing, TransCommand active transmission safety protects the GM Allison 10-speed gearbox from premature wear. It detects gear shifts in real time and momentarily trims torque to prevent clutch and converter slip. Meanwhile, ActiveSafety diagnostics check MAP and fuel rail pressure signals 100 times every single second. If the module ever loses power, hardware bypass relays smoothly restore stock calibration without triggering limp mode. Owners of newer trucks can also upgrade with the 2024-2026 Duramax 6.6L Tuning Bundle for Global B platforms.
