Christian,

Be reasonable here. We are talking about very short Hockenheim Klein Kurs here, not extremly long track a la the Ring. 1s is a huge difference on Hockenheim Klein Kurs. And no, I do not belive that 991TS is 0.9s faster then 991T on flat and short Hockenheim Klein Kurs.  

Do you know what is the difference between 0-300km/h for 991TS and 991T? Only 0.8s...
