        Dan: I know you're new to the 20 valve turbo engine so we need to cut you some slack. However, you really need to read up on how this engine works. I suggest that you go to Scott Mockry's website for the 3B and AAN (similar to the ABY engine). In particular, for today's "lesson", check out the "waste gate controls" section and the waste gate function schematic in the red area on the right of this page:

        I am sure it will help.
