Yes I call the stock 991 TTS a 2door Panamera haha. Whenever you are ready!
2 door Panamera - LOL - that was a good one - I was shocked when I pulled the seat back all the way and could not reach the pedals - amazing how big it is inside - sat inside a 2 door AMG benz and had no room at all

I agree with you - I think the by Design Stage 4 can be a daily driver and break records at the same time - it is a good combination and the Porsche Turbo is a great platform

There are a few virtual dyno sheets around - the main thing that makes the car fast on the street is the area under the curve - it spools up fast and holds the power till red line

I have not gone on a chassis dyno and probably will not as I do not drive on a dyno I drive on a road

I meant more for confirming/measuring HP/Torque figures. All good....we have a similar setup, so 750 engine hp is pretty accurate.

I find that dynos are most useful for tuning aides to compare A - B tests of modification changes or tuning adjustments to set the MBT at various areas of the power band

As far as peak power and now much power a car makes - dyno to dyno variation based upon the settings of the configuration of the dyno and air temps etc can make significant differences from dyno to dyno

For these reasons my best method to test my power is by trap speed and scale weight at a drag strip, that gives you a great idea of how much power you are making

Too many people get hung up on dyno read outs and do not realize the nonsense that goes on in the tuning world with correction factors and settings from dyno to dyno

Vehicle race weight and a Trap speed will tell the TRUE story better than any Dyno will.

Though, similarly, a day at the strip can also see a ton of variables thrown in - magnifying discrepancies on higher horsepower turbo cars..

Traction, DA, heat soak while queuing, launch surface, driving style / shift speed, etc, are all factors - so one ideally needs to make 3-4 passes to establish a relatively accurate baseline for power estimates.

Dynoís can be manipulated and subject to variables, yes - but a well known dyno with some reliable baselines for your own car, or other stock examples of your car, can also be startlingly accurate.
