The manual gives different break in procedures for the 991.2 compared to the 991.1. Previously the wording gave "hints" and "tips". Now the wording says "must be run in".
The 9A2 engine uses plasma beam iron-coated cylinder liners for reduced fuel and oil consumption. Maybe this new technology requires, or possibly requires, different run in procedures.

Porsche has published the torque/power curves versus RPM for the cars, along with the gear and rear axle ratios. I thought it might be interesting to use this data to replot power versus speed in each gear. I used the MPS4S rear tire size of 764 revs per mile.
For max acceleration, redline shifts appear appropriate in the first three gears, and then slight short shifts seem to be required for the next two gears. Redline speeds in each gear for the S are slightly less due to the larger rear axle ratio.
Just found this old thread on a search, surprised it stopped getting posts. As the title could just as accurately be "9A2 3.0 Owners", it has good focused data and links, still relevant to the pool of active/recent 991.2 Carrera buyers (new leftovers, late allocations and CPOs) which includes me-- so thanks to the original contributors.
Coming from another 9A2-gen P-car (718 Boxster S) which had me poking around here and ************.com, I'm already familiar with most of the thread content, but was able to save off a few good graphics. My path to the 9A2 3.0 has been:
928S4>Ferrari 328GTS>996.1>996.2>987S>982S>991.2 Carrera S
Just got a 2017 991.2 with PDK. It is a 2 year lease car with CPO and 18K on it.
After the car is first started there is a lot of noise that is mechanical for the first 30 seconds or so when at fast idle. Then, once that cats are lit, the car goes to normal idle speed and the noise disappears.
I assume this is the various engine systems working to get the cats up to operating temp ASAP. However, I have lots of other cars, and they do not exhibit this type of mechanical noise during the initial warm up phase.
I have seen posts that seem to state this is normal, but would like to confirm.
