k. so i figured out why my cars getting no boost (97 a4 1.8t quattro) the black rubber hose coming from the turbo looks like its been cut? and is running to nothing its just floating by my airbox. can anybody tell me what its suppose to be hooked too? theres also another hose just like it that looks like its been cut, almost as if something is suppose to be there connecting the 2.

 

that hose is suppose to go.... turbo to n75 to the wastegate. You need to complete the loop.
