Put the snorkel back in?

I have a 2005 VFR: http://vfrworld.com/threads/returning-member-2005-vfr800a.54481

The previous owner installed a Power Commander and removed the snorkel but gave it to me when he sold the bike. My understanding is that this might rob me of some torque.

1. Should I put the snorkel back in?
2. If I do, should I also remap the Power Commander?

 

I had removed the snorkel and found that it really didn't do anything but increase intake noise. At the time I also had a Power Commander and it didn't really make a difference to it. I now have both the snorkel and air box flapper in place.

 

Nothing wrong with some evil, bloodcurdling intake music.

 

I've done lots of mods to my bike, most to improve it.
I've reinstalled the snorkel as I found it made no difference except noise, and making it easier for water getting in there.
