i just dropped the k&n in because it started with the stock filter. i even tried putting the stock exhaust back on and resetting the computer, but no go. so, i think i need the power commander if i really want to fix this problem. been looking on the website and i'm a little confused...it shows maps for certain exhausts and certain riding, but none really match my needs. is there a way to set it regardless and are the maps free downloads? thanks for any info
