Default Waste gate crack

When im into it about 40-50% throttle my turbo will spool but for about 2 second it makes a kind of noise then it goes away and will spool normal. I had my friend look at it and he believes its waste gate crack. Im running the stock vf39 turbo with 78,000 miles on it. So is waste gate crack a big problem?

Nope. It's probably your wastegate fluttering. I have this on my car, it's more of an annoyance than it is a problem.
Does it sound like a helicopter going tsk tsk tsk tsk tsk?

It's not a problem at all...it's just the sound of the wastegate working.
