Need some MAF part numbers please

[TDSAaron]

I just finished my S14 SR swap and it's running good except it's a little lean at WOT. The MAF that was installed on the clip and the one that's on the car right now is 22680 69F00 AFH50-18. Part throttle AFR's are a little lean and around 15.1:1. WOT stays at around 14.1:1 until about 7lbs and 4K RPM when it finally makes it's way down to a 12.1:1. The car does not make over 8lbs of boost and has the stock boost solenoid installed right now.

The other meter that was laying in the floor of the clip has a part number of 22680 52F00 AFH50-13. When I try it the car is pig rich at idle and won't even stay running. It was around a 10.0:1.

I have searched and been unable to find a cross reference for these stock meters. Can anyone help me out by verifying a known Stock S14 Blacktop SR MAF part #? Thanks in advance.
