Hissing and hard starting are the usual signs of a vacuum leak, and those are most ofter caused by a aged/weak vacuum hose that finally breaks off where it is connected. I'd be very surprised if it is anything else. You'll probably note that your boost gauge does not go as far to the left as it used to. Of course the good news is it is inexpensive to correct. Give the engine compartment a thorough look and trace EVERY vacuum hose you see from one end to the other and I'm sure you'll find it. The hard starting suggests it is a sizable leak.
If the unlikely result is you do not find a vacuum hose leaking, you might also check the large rubber hose connection between the turbo outlet and the intercooler inlet located very low on the passenger side of the car.
