Wills, this might come across as a contradiction, but I agree with you even though last week I got my 140 mapped to 175.
It's not that I wanted to go faster, I'm a steady driver, but I wanted the whole driving experience to be a bit more relaxed, and it is. I find that I can hold on to a gear now, without labouring the engine, whereas before I would have had to change down a gear, for a slight incline. I also often find myself changing in to a higher gear just a little bit sooner when accelerating, without using more revs to get there.
Basically it is the extra torque that is probably more important than the extra horsepower.
