S90 V90: T6 + PoleStar performance

[driver219]

I have driven this V90 estate for 3 years now, and it is indeed a mighty car, in comfort, in performance, in silence, in handling, in looks, in functionality and in safety. It is a beautiful car in all those aspects. There's one small criticism, and this is, in High Performance mode, unless one chooses the right moment on the power curve, when one accelerates hard the mapping sometimes seems to dither over which gear to select.

Now I've just had the PoleStar software fitted, and I was dubious, having read the listed minimal improvements in performance, given that the performance is mighty anyway!! But now the car seems to have tightened up, just as silent, just as comfortable, but so much more responsive. And very little difference in insurance premium!! So why wasn't this offered at the time of purchase??
