Any chance of some comments about the feel of the car before and after the installation of the HPP..
Thanks

Important things first: forget to experience any change in day to day driving and forget power oversteering.
For how the S3 system is built, it is impossible to have the rear wheels spin faster than the front ones, so no power oversteer.
In low grip conditions (road has to be very cold, or damp, or (even better) wet) you will experience a tendency to "close" the corner when you apply power, but you have to apply it all of a sudden, and even so you will not need to countersteer, just decrease a bit of the steering angle.
On the snow the car will be more predictable but, again, to have it oversteer you will need to go really fast, and on snow it's not healthy...
It dramatically changes the way the car drives, but only when you are close to the limit. At that stage, it literally throws you out of corners and delivers faster laptimes.
When you are in the middle of a corner, with all the tyres squealing and you hammer it down, you clearly feel the back of the car commiting to deliver everything to the road and the car starts to slide a bit on the four wheels, and there you go, towards the next corner with a big grin on your face.
You will soon forget that nasty understeer when you apply power out of a corner.
