Does this sound like a boost leak?

Just had my timing belt and water pump done. Turbo noises seem way louder than I remember and I feel like the car doesn’t feel as quick as I remember. Usually have no problem kicking on the traction control light if I punch it - lately no traction control light and the car feels a little sluggish.

See video - when I go WOT I’m getting what sounds like the A/C turning on from the engine bay. https://streamable.com/dwkoe1

I hooked up my Cobb AP and the most boost I am getting is around 18.3. Any thoughts as to whether or not it seems like I have a boost leak or if I’m just imagining things?

2015 ST with 70k miles with stage 1 Dizzy Tune. No CEL, idles fine, no excessive smoke from exhaust.
