Description

The Big Gun TFI Power Box is an EFI tuner designed to optimize fuel delivery for improved performance. It allows for adjustments to the air/fuel ratio, typically without the need for a computer. It's often described as a "plug-and-play" unit. This product increases horsepower and throttle response, installs in minutes, features third-generation technology, and does not interfere with the stock ECU map. It comes with integrated faceplate buttons for easy adjustment and is highly recommended for any EFI unit with an aftermarket exhaust. It includes a 1-year limited warranty.
