When you slipped your air filter into the turbo inlet hose,did you remember to first install a 1" wide piece if 4" exhaust pipe? This is so while you're tightening down the hose clamp,the connection of the air filter to the turbo hose doesn't collapse causing unfiltered air to get in.
side note: The first time I put my 0880 on I also had to put my silencer ring back in... way too much noise! I have since installed a Psychotty and can't imagine anyone ever enjoying the silencer ring removed while running the Psychotty.
