Big Gun 16-19 Polaris RZR XP TURBO/S Power Box

Big Gun is known for making performance exhaust systems for powersports vehicles, and their TFI (Throttle and Fuel Injection) Power Box is a solid addition to that lineup. If you've upgraded your exhaust on your 2016-2019 Polaris RZR XP TURBO or XP TURBO S, this module helps you get the most out of that setup. It works by fine-tuning your engine's throttle mapping and fuel delivery, which can make a noticeable difference in how the vehicle feels when you hit the gas.

What this means for you is sharper throttle response, smoother power delivery, and a nice bump in mid-range torque. It's designed as a plug-and-play unit, so it connects directly into your EFI system without altering the stock ECU map, and you don't need a computer to make adjustments. The integrated buttons on the faceplate let you tweak settings right on the box. Big Gun built this module to be durable, with rugged construction and weather-resistant sealing to hold up to the demands of off-road riding, and it comes with a 1-year limited warranty.
