well i got the 04 636 and got the k&n filter, two brothers pipe, and the pc3.. when i put all this **** on my bike i downloaded the map off the web site for the pipe n all n it dose good, but i wanna play with it n see if i can make it any better. maybe a diff map n see if it makes a noticable diff. i heard of people sayn they run the acrapovic map with an exhaust of a diff brand... n people sayn they run a custom map someone sent them, maybe one they had dyno tuned or something. i paid all this money for this stupid box n wanna have some fun with it. dose anyone have a custom map for their 04 636 or a suggestion for the best map or anything? i love hearing what anyone has to say.
