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, coolant temperature, and EGT, just like your engine's ECM. It actively and safely optimizes calibrations in real-time thanks to its OBD-II connectivity. No competitive product does that.

Derringer has 6 levels, adjustable on-the-fly using the iDash. Level 6 produces best-in-class performance. Level 3 is designed for work use and has a great mid-range feel. When running Level 3 with a loaded 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 DataMonster® or iDash® SuperGauge. The Derringer connects in line with your truck's engine sensors. But unlike other tuners, it also connects to the vehicle's OBD-II diagnostic bus.

ActiveSafety health monitoring circuitry: 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 preferred power level.
