WMI Nozzle location before or after IAT?

I know this is old issue
But I still need to know.

IIRC you would want the WMI before the IAT so that the ECU can adjust for the cooler charge temps. You are not going to tune for the WMI but the car should be able to tweak itself based on the charge temps.

Someone correct me if I'm wrong...

Edit: See Tom's post below

Here is why I dont like the WM hitting the IAT sensor , the WM doesnt cool all the air to the temp that once the IAT gets wet shows the ECU it is at so a good bit of timing could be added back in but the air isnt actually as cool as the IAT shows , this could be an issue and cause an engine failure
