When it comes to fuel injection, BOSS has you covered. Using the BOSS TFi digital fuel control box, dialing in your fuel injectors has never been easier! Instead of using the traditional carbureted setup (tapping into the main fuel line), you simply plug the BOSS TFi into your stock injectors. Once this is done, the BOSS TFi and BOSS NOSS Smart Box can talk to each other. Right when you hit the nitrous activation switch, the BOSS TFI instantly fattens up your injectors and adds a regulated amount of extra fuel to your motor.
The BOSS TFi has two separate circuits for use with or without nitrous. For normal riding, you can richen the fuel mixture depending on the performance modifications that have been made to your ATV
