Yes, Mark is saying the same thing.
Since you read the inlet temp just before the engine (as is best) then you read the final effect after all intercooling attempts.
Spraying before the chargecooler simply reduces it's efficiency, because it has less temp differential to play with. The upside is that because it works less, it will not heatsoak as quickly as it might do if it were alone.
Spraying before the chargecooler is sometimes desirable, say when the chargecooler is undersized for the amount of boost/airflow it is meant to handle. There are no hard-and-fast rules, it all depends on the particular setup. :smile:
