I agree - the advantage of the turbo only really comes in when you can use it to produce more power from a smaller engine. This allows for less internal resistance from the engine itself. I think most gains people see are probably due to the typical non-turbo diesels running a little richer than needed and not enjoying the benefits of a complete burn.
