TFI POWER BOX
When installing an aftermarket exhaust, 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 motorcycle, ATV or Side x Side 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.
Our TFI Power Boxes come pre-set with a middle of the road setting already compensating for the aftermarket exhaust. Generally, about 80% of customers that we speak with don’t feel the need to adjust any further after installing it. That’s not to say you can’t fine tune and try to change adjustments even further if you feel comfortable.
