Your fuel injected ATV is equipped with an ECU that's programmed to deliver fuel to the motor based on an air/fuel ratio for stock air filter and stock exhaust system. While the ECU can self-adjust for environmental factors such as temperature and altitude, it can't adjust for mechanical changes like adding performance parts. When you install a performance exhaust system, your airflow changes, so you need a fuel management system that adjusts your air/fuel ratio to match the changes. That fuel management system is FuelPak. The perfect combination with your performance exhaust system.
