Description

The Big Gun Power Box is a plug-and-play fuel controller designed to properly tune fuel-injected motorcycles, ATVs, and Side x Sides. It installs in minutes and allows for easy adjustment via integrated faceplate buttons without needing a computer. It is highly recommended for any EFI unit with an aftermarket exhaust, as it helps cure lean conditions and increases horsepower and throttle response. It utilizes third-generation technology and does not interfere with the stock ECU map. Comes with a 2-year limited warranty.
