[urq] Help me with my Boost pressure testing methodology

[Brandon Rogers]

I use a compressor and shut it off while testing so it does not kick in.  I 
also regulate psi to around 10+ psi.  And lastly I use a cheapie stethoscope 
from a FLAPS - where the end is just a length of small diameter hose (like 
that1.5mm stuff throughout the engine bay).  When air travels across that 
hose tip - you'll know it!  Often times you can hear a whistle or just the 
hiss tho...
