Question K&N/PC III Map Question

I purchased my 919 with a Two Bros. Carbon Full Exhaust System (Single Side). It also came with a PC III, which I never really bothered with because a map is provided within the PowerCommander database for such a setup. However, the map is for a TBR Full Exhaust system and a STOCK air filter. I recently put a K&N air filter in the bike. Is this change enough to throw off my map? I really don't want to spend $250 on a custom map, but I also don't want to be messing stuff up.

If anyone has any ideas or experience with the difference a K&N filter might have on a standard PC III map, I am all ears...

I would think that the added air flow would require a leaner mixture of fuel. I am probably wrong though.
