That trick new exhaust system you just shelled out big bucks for sounds and looks the business, but it might have actually hurt the performance. But how? Altering the amount of airflow inside a motor with mods like aftermarket exhausts and air filters can actually cause a bike to run worse if not properly tuned.
Even stock motors can benefit from adding a fuel management system when used to create a custom setting for specific conditions. Factory fuel settings are designed to pass emissions restrictions in conditions ranging from sea level to high altitude, dry air to high humidity, and even different grades of gasoline.
Considering all of these factors it's no surprise that the stock map ends up compromising power to maximize flexibility.
OK, so a little fuel management box isn't very glamorous. Hell, it gets tucked away out of sight anyways, so there's nothing to even show off. It won't make your bike louder, lighter or shinier. But it will help produce a faster, more efficient and smoother running ride, and who doesn't want that? Adding a fuel management system to a fuel injected motor adjusts the amount of fuel that enters the cylinder. Systems can range from very basic to extremely complex, and the prices reflect their functions.
