Banks all-new Derringer High Output tuner brings the 2020-23 Chevy/GMC Duramax 6.6L from 419 hp and 835 lb-ft to 523 hp and 1039 lb-ft. The system includes the all new iDash Data Pro Powertrain Information Center with mobile app. The Derringer system communicates with the truck's ECM to adjust the tune in real-time, even compensating for altitude. Patented ActiveSafety circuitry protects the engine and transmission. Controlled by Banks iDash Data Pro Powertrain Information Center, the most advanced automotive evaluation tool.

All Banks instruments are warranty friendly. No trace is left behind after removal.

Derringer has 6 power levels, adjustable on-the-fly, with a best gain of +117 hp pushing power well above 520 wheel hp to the road. Plus, the massive increase of +225 lb-ft of torque is situated right in the heart of the power band where you need it most.

Level 6 produces best-in-class performance, while Levels 2-4 are optimized for work use with great mid-range feel with a loaded truck or towing a trailer.

The Derringer High Output outruns the Edge Pulsar, using less fuel and maintaining lower exhaust gas temperatures.

Thanks to the Derringer High Output's more precise tuning between the engine and the transmission, the 0-60 distance is reduced by over half a truck length compared to the Pulsar and almost two full truck lengths over stock. That's a distance of over 35 feet.

The Derringer HO maintains 10% cooler EGTs than Pulsar in our repeated tests. You do not want a tuner that adds fuel without additional air. An over-rich tune results in high exhaust temps and increased soot productions.

To maintain peak performance, EGT must be monitored and kept below 1550°F to avoid engine derate. This is when the ECM protects the engine from high temps by reducing fuel injection. In other words, the engine makes less horsepower when you need it the most. Imagine towing up a grade at altitude during the summer. The Banks Derringer-powered truck will outrun the Edge Pulsar truck when its EGTs climb and the ECM withdraws fuel to help cool the engine.

The real-world benefits of powerful tuning done safely and reliably really show when you’re hauling a heavy load. At peak power, Derringer HO runs 10% leaner than Pulsar at its peak power, resulting in 6% better fuel economy.

Competitive products have been shown to over-fuel when under load which results in increased heat as well as loading up the diesel particulate filter (DPF) much quicker. The more the DPF is full of soot, the less time the engine will make full power. And, more frequent regens shorten the life of the DPF.

• Exhaust Gas Temperature (EGT) — Monitors EGT and intelligently modulates fueling to maintain a safe maximum EGT, protecting your turbo and engine.
• Altitude compensation — Senses ambient air pressure, controlling the turbocharger to maintain power as altitude increases.
• Coolant Temperature Monitoring — Maintains safe power based on coolant temp.
  Derringer does not add power below 160°F or above 240°F
• Full Power Timer — Allows for 30 seconds of wide-open throttle before transitioning to the recommended power level for sustained tow/haul.

Derringer is the only tuner available with Active Safety® health monitoring circuitry:

• Internal diagnostics checks the system 100 times per second
• Checks MAP and FRP signals and monitors CPU activity
• Activates in the event of failure or loss of 12-volt power
• Bypass relays smoothly return stock power with no loss of power or "Limp Mode"

Derringer High Output is calibrated to modulate power during shifts for better clutch engagement. Thanks to its OBD connectivity, Derringer knows when the GM/Allison 10-speed transmission is shifting gears. It reduces its added power momentarily to allow for a smooth shift. Competitive tuners have no idea or simply ignore when the transmission is shifting and continue to add power, overspeeding the transmission and causing long-term damage.

• Intelligent Shift Tuning — Gear shifts are optimized for each power level to protect the transmission and increase shift speed while protecting against torque converter and clutch slip.
• Accelerator Pedal Monitoring — Rolls in additional power progressively, optimizing for both part-throttle fuel economy and maximum power when you want it.
