Screw it in= richer
Screw it out=leaner


If you screw it in, more of the air must go through the AFM flap and be
counted, so the ECU is seeing a higher air flow reading. So the ECU will add
more fuel; richer.

If you screw it out, air is bypassing the AFM flap, so the ECU is seeing a
lower air flow reading. So ECU adds less fuel; leaner.
