The tuner you're using should go through all of this for you, no-one else, as it can depend on how it is being tuned, how good they are, whether or not they are using someone else's file which will need their specific products used. If they are using a promaf tune for example, then it'll have to use that unless changed, same with the injectors.
The main re-seller file I have seen is set up for about 470hp using stock maf though fyi.
