i was driving and everyhting was fine,tial 38mm wastegate was loud,i can hear blow off...all of a sudden i cant hear either of them after i floored it ones,i dont have a boost gauge connected but i can feel the boost building.can anyone tell me why i cant hear them anymore or what the problem is?

thanks

 

The vacuum line blew off. Did you pop the hood to check it out? Why don't you have a boost gauge?! You have a non-operational wastegate and no idea what your boost actually is?

 

ok thanks for the help,it all works again,problem solved-pipe came off,i didnt see it when i checked it out,then i was doing something and i ran into it,ill open my eyes next time.thanks
