I've noticed that when the car is warm, there is plenty boost and my CEL goes away for a while. I removed the plug (circled in the picture) and all of a sudden the car was running like a champ with lots of boost and the CEL was gone! Unfortunately it came back...could that be an issue?

That is the CCV heater. It heats the air hose so any moisture in there won't freeze and block the crank case vent hose. Do you mean the other plug? That is the MAF.
