Well i've noticed that since i've hit 2000miles the car is now getting significantly faster. If feel a lot more responsive and putting your foot down the power seems to hit quite a bit earlier now.
I think you have to be careful when talking about the power of the

In the right band (above 3000-4000rpm) the car is very quick, but if you run it about just below that band then the car doesn't feel very fast, but that makes it great for pottering around town, and if you want the power drop back a gear or two and off you go.
