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.
