If the car "feels" better for whatever reason, is that not the ultimate goal of any modification? We drive these cars because of the way they make us feel - enhancing this is what any modification strives for.
There are any number of mods that do nothing for speed, yet enhance the enjoyment for the driver - it's often these intangible things that "science" can't capture in a graph or simulation.
my $ 0.02 worth anyway.
Your point is absolutely a good one. There is nothing wrong with striving for a feel.
However do note, simulations capture such an effect perfectly well. In this case you can see it by higher in gear accelerations, improved in gear times for speed x to speed y, but a mix of improvement and losses in most multi-gear metrics.
