Its been a couple of weeks since I fitted it. Had a problem with fitting it, mainly due to my stupidity but a quick call to the Superchips help line sorted it out and everything went smoothly.
Performance is much better especially above 4k rpm. The other day my brother actually said "That is faster than mine". His being a Cooper

. Various cars have fallen victim to me now everything from a Honda Jazz with an obnoxious teenage girl at the wheel speeding away from every light she could. The smile was soon wiped off her face and replaced with a "whats lohen.co.uk?" look. A park lane cooper also suffered a similar fate as did a modded Fiesta Zetec S of a friend of mine.
On a different note, fuel consumption is better, managed to get 30 extra miles from the latest tank.
