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. |
a little occasional hard driving on the street isnt really what i would call hard use of a sports car. i also wouldnt consider the 1m a sports car, but that is neither here nor there.
i dont think you can feel the extra 20lbs, especially not in the type of driving you are talking about.
what i do think is that in that type of driving, it is proven in logs all over this forum and other forums that you will likely be encountering timing drops and pre-detonation to possibly detonation events with the stock FMIC even on the stock tune.
the much lower IAT and resistence to heat soak gained from a 5 inch FMIC massively outweighs whatever possible negatives gained from an addiitonal 10-20lbs over the stock FMIC.
i still firmly believe there is no way you can notice any negative effects from 10-20 lbs added on the street driving like that.
I also think its a major mistake to assume all is good under the hood by "feeling" like there are no negative effects from the stock FMIC. Real proof comes from datalogging. You will absolutely take stress off your engine and run smoother in those, or any, conditions with an upgraded FMIC.
