Well then why not go for the max mods you can....get a filter, drill the airbox and filter bottom and rejet. You'll get a good bit more. I can tell you that theres a healthy difference between my bike how it was with the stock filter and no drilled airbox and how it is now after i did those 2 things and rejetted for them, mainly the needles. It brought the acelleration up to where i was finally happy with it. I used the UNI filter tho. From all i've read it seems as tho it's better at trapping particles and still flows much better than stock.
