BMW E53 X5 3.0D Blanking query

blanked the Vacuum hose from the EGR today with a m4 bolt

since I have noticed the smoking on start up has gone and also car runs ALOT better

one question though is when on high revs the car now hisses a bit like a dump valve

could this just be a bit of air leaking out from Vacum hose>?

TBH it sounds very beastly
