turbo bar display

[Stephen Siblock <steve.siblock@sheridanc.on.ca>]

What should typical bar values be on the computer display panel on my 5000CDt
say for those times when I tramp it (like a highway on-ramp at 3 a.m.) or 
during a lane pass at 120kmh.  I have a feeling mine is very low.  Never 
goes above 1.2  Once I saw it at 1.3   And if I hear a very very slight 
hissing sound (almost like a buzzing) coming from the area of the turbo 
or near the fuel distributor lines, does it mean I have an air pressure 
leak?
