I love mine and they have been on for a year without any problems. The oil drains leaked a little and I just tightened the clamps and it has been working great. I just used the spring in the wastegate to regulate the boost and when I want max boost I run boost to the top of the waste gate. I have a lot of pics in the readers gallery. I haven't been reeding much lately. I got a lot of help from the people on this board.
