problem: Why at idle the car seems fine, but when you rev it into boost range(3500rpm-higher) the car runs like crap and my boost gauge only see's 1-2psi. Could there be a crack in my turbo assembly or around the wastegate to cause these problems?

Thanks,

Andrew

 

Have you checked your vaccuum lines?

 

If you are running on stock twins there could be a shitload of possibilities. Your turbos could be going out, there can be a crack in teh manifold, you probably have a boost leak from worn IC hoses, your vacuum lines could be jacked, etc....

 

Well to make things a little clearer, I'm non-seq., have checked all vac. lines, beautiful manifold, and turbos have 47k miles on them.
