Default Throttle Response Delayed on Lift

Is this a feature or a bug? I notice that when I am at or near WOT, I lift on the accelerator and push clutch pedal in, and, for some reason, the RPMs "hang" there for a second or so before going down. It's like the computer is delaying my accelerator lift.

OK that is interesting. I really have not driven anything newer than 2004 car until my Cayman - maybe this is something everyone else has gotten used to.

Does everyone else let off the accelerator for a second before pushing the clutch at max acceleration? God, what a BAD BAD BAD design, having to do things "ahead of time". This is the first disappointing thing about the car - having to "delay" my clutch to accommodate for the very slow throttle response.

I did not have any issues like that with my 09 S, maybe get together with another Cayman owner and compare?

Whatever it is - it's definitely intentional by the ECU - happens very repeatably when I go from full to zero throttle input. Have not tried to see if sport/non-sport mode changes this, or if less than full throttle eliminates it.

Driving like I have always driven a stick, the revs race higher because it's as if I didn't lift before clutching even though I really did. I would definitely be hitting the rev limiter if I were really banging on it, which I'm not, but man what an annoyance. I am not very jazzed about having to wait .5 seconds between shifts to avoid the engine revving higher when trying to go fast.

Take it to your local dealer or indy and ask the tech to take a ride with you and get their thoughts.
