The quick answer is leave it on. The MAF needs that screen so it's calculations won't be skewed.

Yes, you can remove the TB screen. Should you? Nope. People starting doing that a couple years ago because they thought it would improve the air flow. While it does do that, it will allow the incoming air to create turbulence and cause erratic MAF sensor readings. So while your car may run a little better because of a very small amount of air extra, it will run worse because it won't be able to meter the air accurately.
