[Biturbos4] Alternative Boost Gauge Tap-in Location

Hi Keman,

I was wondering about that line last night when I finally had time to look through the 2.7t study guide.  Sounds like that's a better location then either the fuel pressure regulator and the N249.  Now what happens if a leak develops at the bypass/diverter valve line due to the boost gauge tap in?  I think the valves would remain open so air would keep circulating back to the turbo inlet.  Am I even close to being correct?  Any downside you see from this setup?  Thanks for your insight as usual!!
