You want to place the W/M nozzle after the IAT so that the IAT does not get misted on. Reason being that colder air measure by the ECU will increase the fuel injector duty cycle, there by richening up the fuel mixture. This can lead to combustion quench from to much fluid that the spark can't ignite properly.
Let the ECU measure the actual temp and thus air volume out of the turbo and it will do its thing. Then let the W/M cool it down and do its job.
