I was merging onto a highway, I saw open road in front, fast traffic approaching from behind. I floored it, I think I approached redline, I hit the paddle for upshift, there was a distinct pause and then !bang!, the shift happened. I was in M-mode, S6 SMG Setting. It caught me by surprise because in S6 the shifts are usually much quicker. I've been driving this car for years now so I sort of know what to expect. Is it possible that if the car is at WOT and approaching (or reached) redline the SMG pauses?
