from what i can understand
when the throttle is close you'll theoretically produce -1bar(gauge) vacuum
this is due to the fact that the engine is still sucking in "air but there is no replenishment of it from where the throttle closes
think about a paper tube, suck through it and "nothing" happens to the tube
close the opposite end from where you are sucking and watch the tube collapse(due to the "vacuum" produced)
ok
sooo pulling figures out of my arse
vacuum will be produced between 0-50% open throttle(so your gague will read between -1 bar and 0 bar)
at 50% open you'll read 0 bar
when cruising along you'll be say, pulling another figure out of my arse, at 10% open throttle and read -0.2 bar(a vacuum)
so even though you are producing exhaust gases, which make the turbo spool up its probably not enough to compress the intake more than atmospheric pressure
what boost is, from my understanding is the compressor's(apart of the turbo) ability to compress air to MORE than what the atmospheric pressure is, this is a by-product of the turbo's RPM(i think?)
i could be wrong...its just me trying to put what i think i understand into words
