Banks Product Alert
Banks Derringer tuner is now CARB compliant for the 2023 Chevy/GMC 6.6L Duramax 2500/3500. This means that all 2017-2023 L5P owners, including Californians, can enjoy towing and passing with ease. With 81 hp and 144 lb-ft, there’s no more struggling to tow heavy loads uphill. And, as with all Banks electronics, patented safety systems are built-in to keep your engine and trans happy. Still under warranty? Derringer cannot be detected after removal.
