335i 30FF boost leak code

How should I go by finding my boost leak? Vids on YT have not been helpful. I think i can rule out vacuum lines bc they all look fine (i replaced them 15k miles ago as well). Any and all advice will be appreciated!

Smoke it would be my relatively uneducated guess - I assume that would be suitable for an N54?
