And it's not part of the rotating mass.

Sure, but I am also not in favor of putting even the slightest additional weight right on top of the nose of a sports car, of course unless I have real gains (I am with stock tune and I live in a relatively mild climate for the foreseeable future). So, basically my thinking is since I didn't feel any overheating or loss of power issue, even after prolonged hard driving (definition: consistently over 200 km/h and sometimes close to whatever top speed of the car, occasional hard braking and going over those speeds again for durations like an hour or so during which I stay regularly over 4000 and mostly over 5000 rpms, change gears around 6000 to 7000 rpms depending on my mood, basically finishing the gas tank, outside temparatures around 30 to 35 Celsius)-hardest I can do here I may say and usually only once a week-brakes usually feel over heated and a bit noisy (nothing dramatic though) and that's all I can say about the noticeable difference between the end and the beginning of my weekly spirited driving sessions.

So, question is why will I change to a "better" aftermarket IC since I have one which works in "my" conditions, easily the lightest and also potentially with the least lag and best response? As nachob says in his post it also comes with a factory warranty and is already there since I bought the car new

I like to change things and put better ones instead only when I see a need. I will change the stock ic if I move to a warmer location and/or if I tune the engine.
