Banks Power Derringer Tuner w/ SuperGuage | 2020-2022 Chevy/GMC Duramax L5P 6.6L

Stops the competition dead in their tracks. Results in torque and power gains across the full operating rpm range, starting right off idle and marching to the shift point in each gear. Derringer is dyno calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFR, Knock and coolant temperature, just like your engine's ECU. Its microprocessor based electronics are able to actively and safely optimize calibrations in real time. No competitive product does that.

Derringer has six switched settings. Level 6 produces Best in Class performance and knocks you back in your seat. The Level 3 setting is for work use and has great mid-range feel. When running Level 3 with a loaded work truck and/or pulling a trailer, your on ramp merging speeds and passing times are greatly improved.

The electronics are enclosed in a compact housing which is easily concealed and communicates using B-Bus (Banks Bus) with other devices such as our iDash 1.8 DataMonster® or iDash® 1.8 SuperGauge. The Derringer connects in line with your truck's engine sensors. But, unlike others, it also connects to the vehicle's OBDII diagnostic bus connector. A CAN (Controller Area Network) transceiver chip communicates with OBDII or B-Bus, allowing our microprocessor to talk with the vehicle.

Health Monitoring: We monitor the health of Derringer 100 times a second. If the health monitoring system reveals any malfunction, the Derringer instantly bypasses itself, sets a device diagnostic code, and returns you to stock power. Plus, Derringer's special coolant temp monitoring prevents power addition when the engine is too cold or overheated. The Derringer also auto-adjusts power if knock occurs due to bad fuel. Maximum safe power is all automatic with a Derringer - you just choose your setting.
