If you wonder about thick rubber hose, nothing serious would happend. You would have vakuum leak off boost and boost leak on boost. idle revs would soar and you would run lean on idle.
If small hose was leaky it would render BOV valve unoperational, leading to sluggish boost buildup after each shift. Impeller damage due to inop BOV at your bost levels is unlikely. But you would have hight boost peaks in intercooler between shifts which could blow off a hose or two.
Thank you for your time,
