Big Gun TFI Power Box Polaris Ranger XP 800 / RZR 800 / RZR 4 800

Big Gun's TFI Power Box fuel controller is designed to perfectly tune motorcycles equipped with Big Gun exhaust systems. By reducing engine restriction and increasing airflow, it ensures optimal fuel ratios across the RPM range, preventing the engine from running lean. This safeguards against overheating and preserves smooth, stock-like drivability. Its integrated faceplate buttons enable swift adjustments, eliminating the need for external devices.

• Increases horsepower and throttle response
• Includes pre-set map to compensate for Big Gun exhausts
• Plug-and-play harnesses plug directly in line with your stock fuel injector harnesses using factory-style terminals
• No extra computer, phone or tablet required to make adjustments
• Installs in minutes
