Big Gun 10-14 Polaris SPORTSMAN 550 Power Box

The Big Gun TFI (Throttle and Fuel Injection) Power Box is designed to give your 2010-2014 Polaris Sportsman 550 a noticeable performance improvement. This module works by fine-tuning your ATV's throttle mapping and fuel delivery. It's a plug-and-play unit, meaning it connects directly into your existing EFI system without altering the stock ECU map, making installation straightforward and keeping your machine reliable.

You'll feel an improved throttle response right away, with smoother power delivery and a boost in mid-range torque. This is especially beneficial if you've already upgraded your exhaust system, as the Power Box helps optimize the fuel and air mixture for those changes. It features integrated buttons on the faceplate for easy adjustments on the fly, so you don't need a computer to tune your EFI. The unit itself is built tough, with weather-resistant sealing to handle the elements you'll encounter out on the trail.

This is a third-generation technology unit, built for durability and ease of use. It installs in minutes and is a solid option for riders looking to get a bit more out of their Sportsman 550.
