It may come down to preference of means and methods. I don't have a dyno tune (yet, but maybe soon) but I have heard from others more than once that the method I described in my post is usually how it goes. Personally I think that is a preferable way, as then YOU the owner of the car are in possession of your stock tune file and can also have other tunes written for whatever driving purposes (for varying levels of boost, changing out N2O jets, etc) and reflash the pcm as necessary.
