Ok all pointless bantering aside,
Why would the car
increase revs between upshifts. The next (higher) gear you select will cause your revs to drop, so revving the rpms higher will make the rpms difference even greater during the upshift.
Basically, it seems to be replicating the "no lift shift" or "powershifting" which isn't exactly easy on the tranny.
I don't have a Z, so comments/corrections are welcome.
