When I did a log a few weeks ago it was a bit low, the car also feels a bit laggy compared to stock with just jB4. So far I've pulled all the couplers on the driver side and retightened them. Still have a noise so it must be the coupler on the passenger side or an actual leak in the FMIC or something along those lines :/

Edit, I was getting around 11-12 ish psi on map 2. And I'm wondering if the loud whistle is just the turbos working harder than usual to attempt to make target boost.

Just out of curiosity did you try uninstalling the jb4? Not saying it's the issue but if you dont have any noticable leaks it may be worth a try and see if the problem persists.
