The article is an interesting read.
Why was he using an "A2" version on a manual car? for all we know the auto box may have a vastly different "curve" to the Manual box to start with, thus making all assumptions inaccurate for a far comparison of standard against modified.

I can understand that in a manual car the 0-60 would not be affected so much (if at all) as the driver has full control of the clutch and the throttle response would seem pretty good to start with. The Auto, however is not as easy to get off the mark quickly, even if you do "Mash" the pedal or do anything else to it to try to get a fast launch, believe me I have tried every way possible to get this 1.5 tone piece of metal to shift of the mark quickly and controlled. The sprint booster, in my opinion, is probably more suited to the Auto box and as such the difference felt is greater. Theory and practical application are not always as closely linked as you would think. Real life experience is what it is really about.

As I said in my earlier post, I have no doubt that this is a very cheap part to manufacture but the feeling you get IS worth every penny and you are paying for someone else to have done the research into finding the best "curve" for a more involving drive.

I have no regrets over parting with my money for this, I am enjoying the car so much more now, even more that when I first got it. It is so different, you wouldn't believe it unless you try one.
