There are cheaper ways to block it off, see the mods section, you can use a snug fitting bolt in the airbox that does the trick.

Mine felt better with it blocked off, might have just been the annoying popping nonsense was not distracting me.

Over run on a highly tunes sports bike is cool, over run on the Ten is a waste of fuel...in my opinion of course, I actually quite liked it at first but it was nuts with an MTC single on....
