Ya shouldnt do that unless you didn’t upshift. Im able to cruise at that speed
The rs definitely is different. I’ve hit rev limit and speed limit. Rev limit make you think you just popped the motor pushing it that hard. Speed limit is smoothI'm not sure with this car but not all cars have a "rababababa" rev break up sound at rev limit. Some go smooth just like a speed limiter. My 370Z does this when I pass with a 3rd or 4th gear pull. It just smooths and doesn't progress after 7500rpm. Just saying.
Hopefully, the dealer will solve the problem. I doubt I will report back here ... way too many idiotic losers.
