Car surges after boost ? Pls help

Yep. I thought I was going crazy. I've just been playing around with my setup. Each to their own, but if you plumb the vacuum line in before the throttle body, I reckon you going to have issues. The spring adjustment on the bov body is there so you can 'tune' the bov to your setup and vacuum levels. Turbosmart state the same on all thier install guides, and they know shit loads more than me.
 
I've Plummed it back to recirc and it's still has that little surge .. It didn't really make a difference but it did give me more miles

Could it have anything to do with my turbo ? Can blown seals or bearings cause it ?
