I know this is a fairly common question, but its hard to get a straight answer.
What is making it sound like that? A bigger turbo, or an open blowoff valve? I hate open blowoff valves, as they are usually the HKS style one, and it sounds like a loud bird call, but that sounds pretty good.
I use a bov from GFB that recirculates myself, and that one has the classic stock woosh sound, just alot louder at 1.2 bar peak
Does it sound like that, because its a bigger turbo?
