Premium Tuning Device Improves Power and Performance

If you're looking for a clean, safe, and proven way to add real power to your 2020–2023 L5P Duramax without leaving a footprint on your ECU, the Banks Derringer Tuner with iDash 1.8 DataMonster is the tuner you’ve been waiting for. This isn’t just another plug-in box making bold claims—it’s a fully engineered inline tuner that delivers measurable gains, advanced safety features, and full control over your truck’s performance, all while keeping your emissions equipment intact and your factory warranty protected. The Derringer is capable of adding up to 81 horsepower and 144 lb-ft of torque, with power gains felt immediately from idle through every gear. With six switch-on-the-fly power levels, you can dial in the tune that fits your current load or driving situation—whether you're daily driving, towing, or just want to wake the truck up for a fun drive. You can even make power adjustments while the truck is in cruise control.

Integrates Seamlessly to your Truck

What sets the Derringer apart is how it integrates with your truck. It connects not just to the engine sensors, but also to the OBDII system, allowing it to read real-time data like throttle position, RPM, coolant temp, air-fuel ratio, and knock—just like your factory ECU. This allows the tuner to make intelligent adjustments on the fly and ensures you're never pushing the engine outside safe limits. Built-in ActiveSafety protocols also monitor critical conditions, pulling power automatically if temps get too high or poor-quality fuel is detected. Included in this kit is the iDash 1.8 DataMonster, which not only gives you a live display of vital engine data, but also allows you to data log up to 100 parameters at once. With the included 8GB microSD card, you can store, review, and analyze your data anytime. It even shows regen status, Derringer activity, and added power in real-time with a clean, customizable interface. Best of all, installation is truly plug-and-play with no need to cut wires or remove the ECU. It’s easily reversible for dealer visits and leaves no trace in the vehicle’s computer system. And thanks to its compact housing, the Derringer module can be hidden out of sight for a clean install.
