Big Gun TFI Power Box Yamaha YFZ450R / YZF450X

The Big Gun TFI Power Box fuel controller enhances your vehicle's performance following the installation of an aftermarket exhaust. By minimizing restriction, an aftermarket exhaust elevates airflow through the engine. However, this requires fine-tuning to ensure the proper fuel-to-air ratios across the RPM spectrum. The Big Gun TFI Power Box efficiently addresses this need, delivering extra fuel to safeguard against lean engine conditions that can elevate temperatures and disrupt smooth operation. Its user-friendly design boasts integrated faceplate buttons, eliminating the need for external devices to adjust settings, ensuring the vehicle retains a smooth, stock-like feel while benefiting from improved performance.

Features:

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

Note: Image for reference, actual product will vary based on application.
