I disagree, these bikes run somewhat lean from the factory, so you could potentially gain a little with just a controller. You could gain a noticable amount by just removing the airbox lid and pulling the sparky with a stock bike and a fuel controller.DuneMe said:The tuner alone shouldn't net you any gain in power. . .
Simply adding fuel or taking away fuel from the stock bike shouldn't effect your power.
A Pipe and an Air Filter (better flowing) will ALLOW you to add more fuel. . . for that you need a programmer since this is fuel injected. . .
