Banks Power 67107 Derringer High Output Inline Tuner with iDash Pro for 6.6L Duramax L5P

The Banks Power Derringer High Output Tuner (67107) is an advanced inline performance tuner engineered for the 6.6L Duramax L5P diesel engine. Delivering up to +117 hp and +225 lb-ft of torque, this system elevates output from 419 hp / 835 lb-ft all the way to 523 hp and 1,039 lb-ft — all without reflashing the ECM or leaving any trace behind.

Unlike traditional flash tuners, the Derringer operates as an inline microcomputer that intercepts and optimizes engine sensor signals in real time. It connects directly to the vehicle's OBD-II diagnostic port, allowing it to communicate with the truck's ECM and continuously adapt tuning based on live operating conditions.

Key Features:

• 6 On-the-Fly Power Levels — Adjustable while driving or parked; each level is calibrated for a specific use case from daily driving to maximum tow/haul performance
• ActiveSafety® Health Monitoring — Patented circuitry performs 100 self-diagnostic checks per second; instantly bypasses the tuner and reverts to stock power in the event of a fault or 12V power loss — no limp mode
• AutoRate Real-Time Adaptive Tuning — Dynamically adjusts fueling and boost based on throttle position, RPM, vehicle speed, AFR, knock, coolant temperature, and EGT
• EGT Monitoring & Protection — Intelligently modulates fueling to maintain safe exhaust gas temperatures, protecting the turbo and engine
• Altitude Compensation — Senses ambient air pressure and controls turbocharger output to maintain consistent power gains as altitude increases
• Coolant Temperature Monitoring — Prevents power addition below 160°F or above 240°F to protect the engine during warm-up or in overheat conditions
• Intelligent Shift Tuning (TransCommand) — Reduces added power momentarily during gear changes to protect the GM/Allison 10-speed transmission and improve clutch engagement
• Accelerator Pedal Monitoring — Progressively applies power for both part-throttle fuel economy and full-throttle performance
• Full Power Timer — Allows 30 seconds of wide-open throttle before transitioning to the recommended sustained tow/haul power level
• Includes iDash Pro® Powertrain Information Center — Monitors and displays real-time powertrain data with Bluetooth mobile app connectivity
• Plug-and-Play Installation — Simple installation with easy removal for dealer service visits; warranty friendly with no ECM reflash required and no traces left in the ECU
• Emissions Compliant — All six power levels maintain compliance with emissions standards; does not modify or delete DPF functionality

The compact Derringer module is easily concealed in the engine bay and communicates with other Banks devices including the iDash DataMonster and PedalMonster throttle booster via the Banks Bus (B-Bus) network. The 67107 kit includes the Derringer High Output tuner and the iDash Pro Powertrain Information Center.
