When installing an aftermarket exhaust on your Honda Rubicon 500, proper tuning is a must. The Big Gun TFI Power Box is a plug-and-play fuel controller that allows you to properly tune your fuel injected ATV in just minutes. Installing a TFI Power Box allows you to get the most out of your aftermarket exhaust and increases throttle response. A TFI Power Box helps cure the lean issue that is run into when installing a higher-flowing exhaust and comes pre-programmed with a middle-of-the-road setting already into it, making it easy to install and go ride.
