You didn't mention year, but usually a bad coolent temp sensor will cause the idle to sit really high, around 2200-2800 and then dip back to normal.
Pull the plugs! I made the mistake of overlooking the plugs after doing some stuff and it turned out I had a crack in #3 plug. A good test is to remove the center cover on the valve cover, pull in a dark area and look for and spark jump or arcing around the plugs. A few squirts of water showed me my problem. My car would idle great and ride ok, But in boost, buck, stumble and go in and out of good boost.
Also you may want to check your throttle position switch.
Also, check all vacuum lines, turbo boot clamps and connections at the AMM.
