Product Details
This Big Gun TFI (Throttle and Fuel Injection) Power Box is designed to give your 2006-2011 Polaris RANGER XP 700 EFI a noticeable performance improvement. It works by fine-tuning the throttle mapping and fuel delivery, making your RANGER feel more responsive and powerful, especially in the mid-range where you often need it most. It’s a solid option if you’ve already upgraded your exhaust system and want to get the most out of that change.
Installation is straightforward thanks to its plug-and-play design, meaning it connects directly into your existing wiring without needing to remap your stock ECU. You can easily make adjustments on the fly using the integrated buttons on the faceplate, and you won't need a separate computer to dial in the EFI settings. This third-generation technology is built tough with rugged construction and weather-resistant seals, so it can handle the demanding conditions your RANGER might encounter.
