08 Coupe I red line at 7,800 - 8,000 since I had the ECU re set with exaust mods, free flowing air filters and grounding wires.

I have a problem tho, I now own a 2010 g37s 7AT, it doesn't bounce on redline it just stays put at 7000-7500 rpm but I owned a 2009 g37s 7AT that used to bounce off redline crazy! Anyone know why?

It could be something in the programming from year to year. The rev limiter should cut fuel which will make the car bog down. My 08 would bounce rapidly at redline. I seem to recall that my 2012 would bounce but more slowly. Nevertheless I tried to avoid having it bounce at all. It just slows your acceleration.

I’m able to reprogram this behavior when I flash the ecus using ecutek. PM me if you’d like some help with this.
