Well it sure looks like you got me then

I interpreted 1 Bar to mean Barometric pressure not Psi. 1 Bar of boost , "boost" being the key word, means over sea level presure.

But does the ERG valve open when the engine is "Boosted". I thought the EGR valve opened only at lower cruise RPMs when the Turbo was not spooled up. So at what rpms or Man Pressure does it open? The intake is not always boosted is it?
