I would honestly say if it idles high then it might be more of a vacuum leak more than boost. Check all of your vacuum hoses such as the ones on your waste gate since you had to disconnect it when you did the swap. I would say seeing as you were on that side of the motor to work on the turbo then it would be the place to start. Another thing to check is if there is a unburned fuel odor coming from the tail pipe. This would mean that the car was trying to flood because of the vacuum leak. I had the same problem with my 1JZ when I put it in I had to re route all of the vacuum lines because of everything being on a different side and it took me a while to figure out where I messed up.
