I see. Makes sense. Very helpful. I will check the forums.The LSA isn't just a detuned LS9. It has many different parts. A different, smaller, supercharger as well as some different internal engine parts. Different cam.
If you want more power putting the LS9 parts on it isn't a cost effective way to do it at all. You can get more power cheaper and easier through aftermarket pieces. The performance modification section of the forum here has a lot of threads with info on what mods people did to get to what power levels.
