Diesel tuning is similar in that a free flow exhaust and removing any inlet restrictions, and bigger turbo will benefit, but not immediately essential, but that's where it ends,
Petrol engine tuning is done but increasing airflow/pressure so you can add more fuel which results in (everything being equal) more power,
But diesels have a maximum calculated amount of fuel, and airflow is secondary, as there is unless there is a problem always too much airflow, so adding more fuel will result in more power, its almost the opposite of a petrol engine, so to tune its just a question of changing the fuel tables and injection timing (which is the equivalent of changing the ignition timing on a petrol engine).
Pedants are men who would appear to be learned, without the necessary ingredient of knowledge.
