This may be the "new" way of piggy backs and I could very well be wrong as to how they work on the n5x motors, however, many piggy back systems have been offset tunes...similar to a manual boost controller: all it does it leak air from the line that opens the wastegate in order to force the turbo to compress more air (raise boost) so that the wastegate receives enough pressure to open - granted, this analogy is as mechanical as it gets.

Negative, it's not a building block in the sense you are thinking. The new tune does not "stack on top of" the OEM tune. It blinds the DME and gives it's own false parameters to manipulate the DME into raising boost, advancing timing etc. The end game will be the same unless other physical restraints come into play, ie; fuel delivery, timimg, compression etc.

I am not a tuner but I believe that the above is pretty much how it is.
