That it did. Pretty leanish right from factory. I think that should be one of the first mods anyone does to the bike, straight off the bat no other mods done yet. I would liked to have done this first just to see how much more could have been got out of the stock bike with only a better tune in her.
And for only 250 bucks it has to be one of the cheaper mods too. Less cost than a slip on that will give you nothing except sound. At least with the tuner you will have some gain even in stock form and with further mods its only up from there......
