Description

The Big Gun TFI Power Box is a plug-and-play fuel controller designed to tune your machine after installing an aftermarket exhaust, adding more fuel to maintain good ratios throughout the rpm range. It helps protect the engine from running lean, keeps temperatures down, and maintains smooth, stock-like drivability. It features integrated faceplate buttons for easy adjustments without the need for an external device.
