Neil,

	The normal boost is somewhere between 1.3 and 1.4 bar.  0.4 would 
be approx 6 psi boost.  Factory spec is around 6 psi boost, which varies 
depending on outside temp, and the engine's state of tune.  Also, the 
stock gauge is highly questionable.  Mine reads pretty close, but has 
alot of hysteresis.
	You are right, however, the boost level is very low.  This is a 
very conservative system.  If you run it up to, say, 18 psi, you will 
notice a little better performance:-)
	I believe Ned's stage I is 12.5 psi.  Stage II goes to 15-16 psi 
I think.  Eric or Scott should be able to tell you.
