Inlet question

[DeeTurbo]

If I start the car, then take the inlet pipe off the MAF, then cover the pipe shouldn't it choke the engine and stall?

The turbo sounds louder so I did the above thinking I could spot a leak in the inlet system like this.

I'm thinking the boost pipe or the feed pipe might not be connected properly.
