Truck Pulling questions

I was watching videos on youtube. I noticed that the chevy trucks with the duramax engines have the passenger headlight removed.
Anyone know why they do that?
Also why do their turbo make a coo-coo-coooooo when the get to the end, instead of just a smooth cooooooo?

I don't know about the turbo, but they remove the headlight to get more air to the intake.

And I figured it was just something GM forgot to install.

The air intake is directly behind that headlite. That noise is the turbo "barking", which isn't too good on em. The air in the intake system gets backed up from letting off the pedal, and makes the turbo stop and spin backwards. That's the bark you hear.
