Who is and isn't following the Break in period ... 2000 miles ?!?!
I only have a couple of hundred miles on mine but I was wondering who is following the rule of not going over 4200 rpm ...
I have hit 5,000 rpm's a few times but that is about it ... how can you not hit it.
It's going to take me forever to hit 2,000 miles and I drive the car often just not a ton of miles ... do you really need to follow this 4200 rpm's thing ... every other car I have had has been 1000 miles or less and I usually hit redline a few times in between once I hit 500 miles.

Seems to be conflicting advise from even within Porsche. My sales guy warned me about the break in period while the service tech said that the car was designed to be driven like you stole it right from day one!
I will most likely err on the side of caution and keep an eye on the revs as hard as it may be.

I have spoken to two Porsche service managers about the break-in period (they will remain nameless in case anyone is monitoring this forum) - both told me to just to drive it, the only thing that needed to be broken in were the tires for the first 100 miles or so! I have 250 miles on my 991 and one service manager asked if I had tried launch control yet! I don't think he would have been concerned if I told him I had - I haven't.
As an engineer who has been building ultra-high precision machines for 35 years and worked extensively with automotive companies around the world (but not Porsche), I would tell you that the advice to run the car through several heat cycles and vary the RPMs are the only parts of the break-in procedure you should observe for the first 1000 miles. It's not just the engine, the transmission and drive-train all have gears and bearings that need to be properly seated. I also believe it's important to pull some real torque through the RPM range during the so-called break-in period.

9 Porsches later .. here's my break in period !!!
1) I get the car and pamper it a little at first . I learn the car a bit . The car gets to learn my drive style too .
2) An occasional sprint AFTER the engine is fully warmed up but no excessive hammering at all.
I modded my cars within the first 200 miles .
I never hada blown engine , or a major problem .
My opinion about the 2000 miles --
It's a great way for the manufacturer to hedge their own warranty costs . Some drivers may only drive the car 1K miles in an entire year . Plus with 2K of expected pampering theres only 48K miles left on the 50K to raise concern .

I only took 1,000 miles break-in with my previous Porsche Cayman S DFI 2011, after that I have changed an engine oil and reved hard till red line, no issue at all. Now with new 991S I reved above 4,200 rpm a few times during 1,000 miles. After break-in, the engine does feel smoother and it is time to rev hard 
But one thing that I always do is, do not rev the car when engine is still cold

Porsche sales guy told me to get on it. Let the dealer lot using launch control
This is a debated topic even among race engine builders. We were discussing it this past weekend at VIR. One engine builder says he is diligent about breaking a motor in. The other says he puts in on the dyno, warms it up and then goes for it.

I didn't follow break in protocol. Used sport+ from day 1. Have done 4300 kms now. The pdk has plenty of safety built in for the engine.
I also still have to take the car in for the recall fix. I'll do that in May some time.
