Default Boost leak help -11 WRX

Mods are

Catback
COBB OTS stage 1
Boost gauge
Oil Pressure gauge

I was hitting boost on a fwy on ramp and I started noticing this weird noise - similar to a failed silent fart.

I just installed the defi boost gauge about a week ago and flashed to stage 1.
(was previously stage 2 w/DP but took that off)

Where does that boost leak sound like it's coming from? I hear it on the left front driver side - so I imagine it's the T connector. I have the T connected mounted about 2.5 inches after the BPV -> T --< Sender & whatever else it connects to lol. I checked the T connector today and it looks okay to me, I took off the crappy zip ties on the tubes and replaced it with 18lb tensile str zip ties but I'm still getting the noise.

Here's a video

I don't think it's the TB --> intercooler because I've had it on stage 2 before and it was all good at 17 psi. I'm only on 15psi w/OTS stg 1

If you look at the video, it rises up to almost 15, makes the fart, then drops to 10 and rises again, and farts and drops.

Any input is well appreciated..
