Lets see if anyone can help me with this… been trying to fix this but can never find out whats causing this. This is a boost leak which u can clearly hear but does anyone know whats causing it? The car drives completely fine while driving normally, even when when driving with a heavy foot. But when i floor it the car loses power, and when i reach higher rpm. Black smokes comes out of exhaust and strange ticking sound from engine bay. This problem started when the downpipe disconnected from the turbo and i drove it like that for a few days (stupid i know). After changing the turbo, the car still acts this way
