Default Very high idle

Is there anything I can adjust to make the miata idle lower?
Had a stock throttle body and a plate was in the way and I couldn't adjust the throttle body nut n small Allen bolt. It was idling at 1200 rpm.
Switched over to a skunk2 64mm TB and it's idling at 1500-1700rpm.
The idle screw is as tight as can be.
Loosened nut, backed off Allen bolt as far as I can go so butterfly is as closed as can be as well.

No vacuum leaks. Besides the high idle the car runs great.

Idle screw completely closed and you have no vacuum leaks? Jumper between TEN and GND and tell me what the car does.

It's running off ms2. Will jumping TEN and GND do anything?
Am I suppose to jump TEN and GND while adjusting the idle even w ms2?

Edit: Just checked again this morning. Jumping TEN and GND and pulling it while running didn't change anything. Idle not at 1500 like last night. Now it's hunting constantly between 1250 and 1000 rpm.

Here's my .msq file.
I'm not too familiar with programming ms2.
Does my fuel and enrichment settings look like it's in the right range?
