I assume that you double checked to make sure that the WG arm is still attached to the flapper. It would take a pretty large leak in the IC piping for you not to get any boost out of the turbo, but I guess it could happen. Pressure test it if you can. Check out the pictures of the testers that I made here http://www.turbododge.com/forums/showthread.php?t=78629&highlight=pressure+testing
They revealed a couple small leaks in my system that I did not know about.
