sounds like youve got a boost leak mate, cheak all your boost pipes, that misfire your getting is the air flow meter getting confused as the air coming in inst passing throught the air flow meter its sucking through somewhere else

Loud hissing noise is a boost leak. Check all your hoses and make sure they are all up as tight as can be as well.
