As the title says, before I hit any boost at all , no matter if I floor it or not, I hear a whooshing sound NOT high-pitched from the turbo. If I floor it, it's still there but within the same tune. Not hissing, whooshing but you can't really notice it because of the usual turbo sound. I have NO boost leaks whatsoever, triple tested with air compressor and tools I have, no vacuum leaks , and no exhaust/manifold leaks, nothing. It doesn't affect performance not even a bit , but this stupid sound is there. It's like hearing the turbo doing it's job. No oil leaks either.. I only found a really tiny small amount of oil inside the exhaust manifold collector but nothing to worry about it as it was very little. I played with the turbo shaft, there is some play but nothing like it's touching the walls or something. Maybe the turbo it's on it's way? I rebuilt it before 2500miles balanced/new bearing etc etc. Any help? It's a tong hybrid running at 1.1 bar
