What kind of peformance change can I expect after installing the SE heavy Breather and getting the Stage 1 download? This is on a 08' 1200XLN. I actually just had the download done today and would like to hear similar experiences. I think it has a little more "jump" to it, I didn't get a good ride in after the download, that will have to wait untill tomorrow. Thanks......

 

are you doing or have done pipes as well? if not you will not notive much... your bike will be taking in more air but not able to get rid of it in as efficiant mannor... you will notive much more with stage1, download, and pipes
