But that does answer my question. In order to get the meth to flow over the IAT sensor you would need to run it THROUGH the SC or inject it right there at the Y pipe onto the sensor. 
Mike,
When I had my single nozzle tapped into the Y where the IAT sits (Initial install), the car did nothing as far as performance. The car didn't pick up or slow down......This is with one 5gph nozzle installed into the Y basically spraying directly on the IAT sensor.....
