Is this a normal sound?

It runs a little smoother but it still sounds like it is gasping a little for air when I push the throttle. Is this normal or do I have a vacum leak somewhere? I shot a video of the gasping sound:

When I open the throttle very fast, I do hear that air gasp a moment before the engine revs up, but it is always like this and no check engine light or noticeable power loss/ sluggishness.... It is even more noticeable after I installed a larger 996 TB but I thought it is quite normal with original air box and intake system.

It is interesting if this is definitely abnormal, I may be missing something and a few horse powers???

Arghhhhh. I'll have to do some inspecting, myself, and see from where my little gasp is coming. (Hint: It's not my wife).
