Derringer has 6 power levels, adjustable on-the-fly, with a best gain of +86 hp pushing well above 500 wheel hp to the road. Plus, the massive increase of +178 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.

For power and performance that doesn't compromise on engine and driver safety, the Derringer Tuner is unmatched in the industry. Armed with Banks proprietary and patented ActiveSafety Watchdog, the Derringer is able to monitor itself to protect you in the event that something goes wrong with your vehicle, or if there is a loss of 12V power. The ActiveSafety feature runs 100 checks per second. If anything goes wrong, the Derringer will bypass itself automatically and instantly revert the vehicle back to stock power. You'll keep full driveability and regular power levels - no need to worry about any limp modes or loss of power.

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, over speeding the transmission and causing long-term damage. With 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.
