which would cause this?

Which would cause the idle to stay low and bog? Boost leak or vaccum leak or both?

What happens when you rev it? What happens at WOT?
could be boost, or vacuum... Have you down a boost leak test?

the car idles really bad. It bogs at 500 -600 rpm. The idle goes up normally and then when it gets close to 2k rpm it slows down. Then slowly creeps up past 2 and then turbo kicks in hard...feel like it has no spooling before turbo come in. i hear clunking noise from the rear as well. I don't know what to do..

Are you venting you bov? Check to see if you feal air coming out the bov at idle? I had a similar problem, my bov was stuck open. I would forsure try a boost leak test. Try to start and eliminate possiabiliites

Do a boost leak test and get back to us. Sean
