VRSF Charge pipe whistle sound

Hey guys, I installed a VRSF charge pipe yesterday and noticed a high pitched sound on pulls above around 70% throttle. At first I thought there might be boost leak due to a problem with the o-rings I reused, but it doesn't seem to be a boost leak because the car's pulling strong and the logs look like target boost is being hit (I don't really know how to read logs well so I may be wrong). I tightened the meth bungs before installing, so I don't think that's the problem either. My guess is that the coupler may be installed incorrectly, so I'll try adjusting it this weekend. Until then any insight would be greatly appreciated. This is currently the only mod on the car and it's running BM3 stage 1. I attached a zip file with a couple logs and one with the sound.

Definitely sounds like a boost leak. Probably not bad enough to noticeably alter performance.

I found time to adjust the coupler and it ended up being the problem. It literally just needed a few more turns on one of the clamps. I'll leave the post up in case someone runs into a similar problem.
