Big Gun 05-14 Polaris SPORTSMAN 700 Power Box

If you've added an aftermarket exhaust to your 2005-2014 Polaris Sportsman 700, you'll want to make sure its EFI system is optimized to take full advantage of the new airflow. The Big Gun TFI Power Box is designed to do just that, making a noticeable difference in how your ATV performs. It works by fine-tuning the throttle mapping and fuel delivery, which helps to sharpen up the throttle response and smooth out the power delivery, especially in the mid-range where you often need it most.

This unit uses third-generation technology and is built to be durable, with rugged construction and weather-resistant sealing to handle the tough conditions you might encounter off-road. Installation is straightforward thanks to its plug-and-play design, meaning it connects directly into your existing EFI system without altering the stock ECU map. You can even make on-the-fly adjustments using the integrated buttons on the faceplate, no computer required. It's a well-built module that's highly recommended when you've upgraded your exhaust system.
