RE: low boost

Are you sure you don't have a boost leak? Any whistling noises under the hood?

RE: low boost

COuld be a few things. 1: your DV is worn and is venting. Or your wastegate could be stuck open...I would check the DV first. Do you have an underhood shot by any chance?

RE: low boost

damn...good thing these turbos are fairly common. Is there shaft play? It could be just oil cooked in there somewhere...can you move it with your finger?
