It sounds like he is having the same problem. Im not very knowledgeable about turbos, but maybe you need to rebuild it? Because it sounds like the motor is running fine off boost. It could also be the wastegate stopped working and burned your turbo up. Or maybe your old afm went bad and caused something to break from too rich a mixture? and now thats why it seems the new one is bad too. That happens a lot, Sometimes you replace a part and it works fine, but you didnt fix it. And then it goes bad a few days or weeks later. Also did you see if you are leaking pressure/vaccum from anywhere? That will also cause a rich mixture, and sluggishness, and bad boost/power.
