i have a third gen with all the goodies and i was running a good nite of 15lbs then after awhile i couldnt get anymore than 5 lbs.the other 10lbs is pushing out somewhere i can here the turbo spool up and after awhile the wastegate open but when i let off the throttle there is no back pressure.on top of this when it spools up it sounds like its pushing air(on the drivers side)through a pipe thats pushed off its coupling,but i consistently check the pipes and they are solid.does anybody know whats goin on?

 

can someone pleez help me?i put post up here all the time and all people think it is something to look at
