All, I just got my predators on,rejetted, got a K&N air filter, had the A/I and snorkel removed. I had the dealership dyno it before and after for me. This is on my 2006 Black Bonnie
The results were as follows: (at the rear wheel)
Max Power = 45.6 -> 59.8 hp
Max Torque = 35.1 -> 47.26 ft-lb

Is this pretty common? Has anyone else done this with the Predators?

Either way, what a difference. I was really impressed with the sound (I could hear it and others around as well), the throttle response and the looks (black slip ons).

I believe the '06 black bonnie is still a 790. If so, you won't believe the difference it will make to get rid of the airbox.

The 06 I was told has the 865.
What does the Air Box even do? Why does it have one?

You tellin' us you own the bike and don't know? It is the 790!!! Only the Thruxton and T100 had the "big" boy in 2006.

The airbox is a very good noise reducer. It also provides "static air" for the carbs to draw air from. It is a pretty good lower front part of the rear fender until it begins to crack from age. It is a good place to mount fuses, relays, etc. until the rubber mounting straps break. It is a good battery box.

However, it really robs the bike of POWER, IMHO. Mine runs better from idle to redline without the airbox. It starts better, idles better, and really pulls above 5500 rpm. I haven't touched the carbs in 20000 miles except to check carb balance a couple of times--no adjustment needed. I get 50+ mpg, and I do not ride like a grown-up.
