The high-flow injectors are best suited for big-bore machines that spend most of their time with the throttle wide-open. That is to say, if you're running the bike at the drag strip, then yes, you'd benefit from a high-flow injector. For street riding, the stock injector is more than sufficient.
No matter what you choose (stock or high-flow), however, you will need to have the bike tuned by a competent tuner once you replace the fuel injectors as the flow rates do make a difference in fuel delivery requirements, even for the stock-equivalent version.
