Big Gun 09-22 Polaris SPORTSMAN XP 850/HL Power Box

Big Gun is known for making performance exhaust systems for powersports vehicles. This TFI (Throttle and Fuel Injection) Power Box is designed to work with your Polaris Sportsman XP 850 or 850 High Lifter to give you an improved performance feel. It works by fine-tuning how your throttle inputs are translated and how fuel is delivered to the engine, making your ride feel more responsive.

You can expect a sharper throttle response, smoother power delivery, and a noticeable boost in mid-range torque. This unit is built to be durable, with rugged construction and weather-resistant seals to handle tough off-road conditions. It's a plug-and-play module, meaning it installs easily without needing to remap your stock ECU. Plus, you can make adjustments on the fly using the integrated buttons on the faceplate, so no computer is needed to tune your EFI settings.

This power box is especially recommended if you've already upgraded your exhaust system. Installation is straightforward and can typically be done in minutes. Please note that this part is not CARB approved and cannot be shipped to California.
