Consensus on whether stock clutch can handle a tuned K16 car?

I have same milage as you 29k on a 2003 996tt , i had purchased a Cobb tuner at 27 k miles and not sure if the guys consider that a tune on a stage 1 Cobb set up, but my stock original clutch is still as strong as the day i started at 23k miles which the car had when purchased 2.5 years ago..

actually i have not seen 1.0 but i haven't really paid attention to boost too much, I'm always looking at tach and speedo . i did catch 9.0 on dash gauge nothing higher, i mainly hit winding back roads , never really on high way.

Joking, I know you meant 0.9.
I found the best place to test my boost is on a long straight somewhat uphill climb that loads the engine.

its not a matter of cranking them down but setting them up properly with a mytivac and then test that both are opening at the same time. manually cranking them without knowng the cracking pressure could lead to overboosting and damage

Yes, let me clarify. They are properly adjusted.

I see 0.8 bar on my factory gauge right now. Although I assume Porsche has some sort of "altitude" adjustment, allowing the turbos to make more boost to compensate for the higher altitude.

Peaks of .8 are normal for a stock car even at attitude.

Boost pressure is from ambient, if your at ambient pressure of .83 bar (like right now in Denver), you are boosting .8 to 1.63 bar. If you were at sea level with an ambient of 1.01 bar, you'd be more like 1.81 bar.
Aftermarket tunes can sometimes ramp it up a bit to compensate if you ask them to...
If you go to something like a Cobb tune, even the stock off-the-shelf 91 octane tune, you'll be hitting .9 or 1 bar pretty regularly.

Both of my Ford diesels (6/6.4l) compensate for altitude - I can see it in the increase of soot coming out of the exhaust...
