I have a 2014 GT3 with 7,100 track miles plus 1,600 road miles. Haven't had the piston misfire problem yet.
Last week, the car went into limp mode due to a cam sensor warning. The dealer mechanics dropped the motor to check the timing and confirmed that there was a timing problem due to some wear on a spacer.
They further disassembled the engine to replace the spacer and I went in today to inspect the internals for evidence of the cam lifter wear that is the primary topic of this thread. There was some barely visible wear of the coating on several lifter arms (#3 was the worst) but it was pretty minor. The master mechanic is going to consult with Germany, but he doesn't think that it is bad enough to be judged a problem. If so, I will report back.
Just another data point for the records.

A friend of mine is running a 2014 GT3 (engine replaced at port) on the first day of a 3-day track event. The car has about 2000 track miles on it and is throwing misfire codes on 2 cylinders.
Codes were cleared but will return after 2 laps. This is a large track (Watkins Glen, NY).
He has limited Internet access right now unfortunately. "Reduced engine performance. Possible to drive on." is the message.
Is this how it begins?
Time to put it on a trailer and head home to the dealer? Ugh.

Not the way you want to start a weekend. Sorry to hear about your friends problems. On the plus side he could win the PAG lottery and get a new 'G' engine.

If it is indeed the top end issue, I would run the entire weekend just short shifting at 7k to avoid triggering. This way you get the most out of your "E" before it's repaired or replaced.

This is very much like failure with a catalytic converter I had last year. I hit the max RPM and it threw the code. Brought it in and cycle the engine off/on and it cleared. Went back out and the same thing happened. After that it would clear. Dealer said I melted the inside of my cat. They thought maybe I had run race fuel, but assured them that I didn't. They never heard back from Porsche as to why that happened.

Thanks for the advice everyone! I've passed all this onto my friend at Watkins. On a positive, note he trailered the car up so if the engine completely goes, he won't be stranded.
We'll see how the short shifting strategy works tomorrow and I'll keep everyone up to date as to what happens after the car gets to a dealer.

First session of the day done with short shifting at 7000 RPM and no CE light. Looks like the weekend is salvaged. Dumb question, but the codes should be stored in memory for the dealer to pull right?
Years ago I had a random misfire in my 3.4l 987 engine that threw codes but the dealer wasn't able to see them on the PIWIS.

Tell your friend to avoid tailgaters in case he goes limp.
