Choose your Tuning

The Derringer Tuner 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, and if it detects any malfunction; it instantly bypasses itself, sets a device diagnostic code and returns you to stock power. The Banks tuner is an amazing way to safely optimize power, just plug it in to your OBII and you're good to go!
