Fuel Controller Question

I have an '08 CBR1000 with a 2 bros. slip on, and a 2 bros. Juice Box fuel controller mapped for that bike, with that pipe and a stock air filter. If I installed a K&N air filter, or did the intake flapper mod, or both. Would I need a new map? Would it throw off my fuel mixture?

No.

Thanks

just fyi ...i heard the actual stock air filter works just as good or better than the aftermarket filter. This was told to me by the guy who completed the dyno on mine. I had power commander and also custom mapped. I'll be posting thread soon with results.
 
I had thought about also putting a new air filter until this was told to me hence saving the cost if the stock was doing a better job.
