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.

Derringer is warranty-friendly. No trace is left behind after removal.

Derringer has 6 power levels, adjustable on-the-fly. Even with the updated stock power figures for the 24+ models, Derringer puts down a best gain of +86 hp, pushing near 520 wheel hp to the road. Plus, the massive increase of +178 Ib-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.

Derringer's added power becomes even more pronounced when passing up a grade, while towing. Passing on the highway with a 20,065 lb GVW rig up a 7% grade, Derringer rocketed the truck from 45 mph to 70 mph a full 8.5 seconds quicker than stock.

Pushing on to 75 mph, the stock tune runs out of steam on the top end while Derringer continues to pull strong. The gap between stock and Banks widens to a full 12.41 seconds and nearly a quarter mile of separation.

We’ve built 26,000 JLTV engines for the U.S. Army using the same tuning approach that we’re now applying to your Duramax. The midrange is where you work your truck.

• 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.

• High resolution screen with ultra-wide viewing angles
• Vibrant high-contrast selectable color schemes
• Higher speed datalog rate
• Expanded memory for nearly unlimited vehicle support
• Over-The-Air updates via Bluetooth

The Banks mobile app for Apple and Android makes setup, configuration, and updating the iDash Pro easier than ever.
