Still disagree.  1.0 bar is "no boost" at idle (or not running), before
the throttle plate.  After the plate will be a vacuum of sorts.  Rev it
up and "no boost" is substantially less.  Like a fraction of a bar. 
Think about it... anyway this comment of mine is irrelevant to
troubleshooting the car, it's still doing something wrong.  btw, a turbo
engine with *no boost*, for instance wastegate stuck open (btdt), is a
real dog.  Not anywhere near as much power as n/a engine.

Obviously something is opening that wastegate prematurely, but it is
still opening and shutting.

we've now exhausted (sorry) my knowledge of turbocharging...
