Run the stock map in it until you get a slip-on/full exhaust system installed. I love mine but I need to get a custom map done. My bike it running pretty rich. I dont have the number of maps available that you do for your bike. Maybe the map that you get for you pipe wil have it running pretty good. One thing that is nice is that they are super easy to dowload different maps into, so you can play with it to get it tuned to how you like it.
