I've been under the car several time inspecting pipes cannot see any leaks the noise I'm hearing is a loud hisss not turbo nice I can her that through the induction the hiss sounds like it's coming from the driver side but cannot seem to locate it ! I assume it's a big boost leak but trying to replicate the noise whilst on ramp is bear impossible any suggestions ??
