Newby to the society

Greetings! Original owner of a 2006 CTS-V. It has barely 40k miles on it. Mostly, it stays covered in my garage. Now that I am retired, I would like to make some mods to it. I’ve done a few small mods over the years. First and foremost, got rid of that damned shift blocker. Added a Lingenfelter cool air intake. Added a Dynaflow cat back exhaust … (made it sound much better). Been contemplating either a turbo charger, or a supercharger. Not sure I want to tear the engine down to make any severe mods … hence, why I joined this blog. Any advise would be greatly appreciated.
