997.2tt already has the bigger expansion intake. As for
ICs, they always make a difference since stock units are
usually not too far from the limit for stock power. But
I suspect it might be more complicated than that.
Or maybe that one car in the test for whatever reason
was slower after 240kms (fuel, ext temp, god knows what
else). So let's wait for some more tests.
100-200 7.5sec is pretty good for stock 500hp!
