2006 Mustang GT random noise question

Alright, so when I have the key on (car not started lol) and push the gas pedal I'm hearing a weird sound that is coming from the engine bay. It sounds a lot like the noise your car makes once a tune is done loading in the car.

Who knows, it may have always done this and I'm just now noticing it. Anybody else notice this?

Thanks.

mods feel free to move if not tech-ish enough...

It's the sound of the throttle body butterfly's opening and closing via the electric stepper motor that actuates them.

Thanks. Never thought about that... I feel dumb... LOL

So I guess the computer opens and closes the TB when you load a tune too.

Do you know what it is? It sounds kind of similar.
