KresoF1:

Example that SA tested got 25.6s for 0-300km/h amd revd till 8000rpm without any problems. 

Just... 488 do not rev till 8000rpm until oil and coolant reach optimal temperature. Same as Blue light warning on 991 GT3.

You can even see the problem with the 488 in various acceleration videos on the Internet. Maybe it is a software failure or a reliability problem. It seems possible that the test got specially prepared cars that are different from customer cars.
