If you carefully read his posts, from what I have seen making mods to my bike, the simple answer is yes you do need a PC5. These bikes are very picky to add-ons. You would not believe the amount of fuel I had to pull from the midrange when I cut my air box. Some things really take you by surprise.
I have learned to never trust the butt dyno as your ears really do influence the opinion of your butt.
If I have a spare 08 ECU and eventually would love to do some hard back to back testing compared to my 2010 Euro ECU and how the 08 behaves before it's hacked. The changes that they do should jump out at me in the data logs.

So, i only really need either a power commander or an ECU reflash so to ensure the engine is running right to protect itself after a mod (I personally have not noticed the throttle snatch issue everyone talks about). Thus I'm guessing that just a PC5 would be sufficient and make future retuning cheaper and easier?
