Adds up to 61 hp and 112 lb-ft. 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.
