Default 17 WRX Idle issue

Put a new motor in my wrx after I blew it up, first start up went great, however I am having idle issues. The idle is staying around 2k-2500 even when it warms up. Currently running a grimmspeed intake, ebcs, and ets exhaust. Any help would be greatly appreciated. Ill link a video of the idle as well.

My idle issues were related to spark plug, mass air flow sensor, and spark plug wires. Did you check that?

Engine also needs to re-learn your driving habits. In the non-turbo impreza you can spend 10 minutes getting the engine to re-learn your idle. I don't know if the WRX can do that.
