Welcome to the forum.
First question, is the MAF connected properly. I know it sounds elementary, but mistakes happen.
The blade is close most likely because you need to rotate the stock tube alittle.
The stock tube is shaped like that to reduce intake noise if my memory serves me correctly.
Did you disconnect the battery as the instructions say? No matter, the light should go off after a few ignition cyles. Don't worry about it for a few days. Your PCM is not used to the higher airflow and that is probably the issue.
Did that come out right, or do I need another beer....
