I did. turns out my turbos were perfectly fine :/ Oh well, atleast now i have a spare set of turbos. Anyways, my issue was the exhaust manifold gasket.
one of my studs broke. (previous dealer repair) and the air was escaping between the flange and the gasket. It totally makes sense tho. The gasket is 5 thin pieces of metal.

Remember the sound you'd make when you put a thick blade of grass between your thumbs and blew through it? Same concept.. similar sound.
