The best way to measure the gain is not the Dyno, it´s real world comparo.
With your system this must be very easy, because you can put it stock by the touch of a buton.
So the best argument you could gave us, is to measure your tuned car, with a stock 997.2 S PDK just like yours. Then make a acceleration test from several speeds, including the use of launch control.
Test 1:
Giac 997.2 S PDK with stock power vs Stock 997.2 S PDK
(See the result)
Test 2:
Giac 997.2 S PDK with "tuned mode +/- 400HP" vs Stock 997.2 S PDK
(See the difference between this, and first test)
If I were in the states , I would be the first to give my car for this test, and if Giac tuned car would gain some considerable distance, I would buy the tuned program in a heart beat.
Is it possible to see such test? I´m sure, if you could show and prove such power gains, everybody would jump on your system.
More than dyno sheets, this is the real way to show and prove your claimed power gains. Anyone here available for such comparo
Atention, I´m not doubting your word, as I said I would be the first to buy it, if the gains were seen and prove on real world cenario.

Perhaps you can clarify this issue for me. If there are no compromises with your re-flash settings, for instance with respect to increased octane requirement, or loss of fuel economy/drivability, why doesn't Porsche adopt your settings? I assume they are capable of figuring this out. I have been given to understand that the OEM program settings are purposedly compromised to satsify a broader range of customers than the aftermarket programs which may sacrifice some parameter such as economy for increased performance, but this does not seem to apply to your configuration of parameters. Is it because Porsche chose to limit HP for marketing purposes?

G.I.A.C. achieves their gains partly from increased ignition timing. If you don't have high enough octane in the car with the added timing, the car will ping, and everyone knows, that's not good...
Ready now!
$1500
You get a pump program, stock program, and a handheld switcher to toggle back and forth between them.

Very interesting.
The switcher, it is wireless? And the program is simply an upload? How does the switcher work? More details please?
So why have other ecu re-programmers not offered a (so simple and convenient) upload vs a send ecu box to them/load/return box? Is there any compromise to the nature of the re-programming? Certain parameters that cannot be altered via an upload vs send back/load?
Thanks a bunch for the additional info!
And for offering another alternative.

Revo has been flashing via OBDII for some time and has a similar device:

Testing on public roads in the U.S. is not as easy as it might seem. Especially in Southern California, where we are headquartered. We have a 30 day money-back guarantee on all of the software we produce so that customers can test before they commit to the software. We even offer on the fly switching back to a stock mode to make it easier (you can even test this versus OEM stock to verify it produces stock numbers!).
I have had GIAC software probably 8 to 10 times in the previous cars and have never had a problem, although they were all on turbocharged cars. It will be interesting to see how much the software affects a naturally aspirated engine.

GIAC, nice stuff! However I have a question for you about the warranty of my 997.2S if I flashed the ECU.
OK, I took my car into the dealer due to a cracked header weld. Porsche had the service advisor call and ask me if I have tampered with the ECU. This is the second time I have been asked this by the dealer. 1st time was when the car was in for exhaust soot issues and oil burning.
I said no and the service advisor said they would have to check anyway. I asked what does this have to do with a header? I was told by the Porsche rep, my service advisor and PCNA that if I flashed the ECU it could cause the engine to run hotter thus void my warranty. Porsche rep and service advisor personally told me that a ECU flash, intake mods, after market headers which for the 997.2 included cats would void my powertrain warranty and electonic engine managment system warranty.
Thoughts?

I sort of hope Softronic claims are accurate that their original file is untraceable for PIWIS but some folks say any re-flash operation resets some timestamps in ECU and if technician will keep a journal of previous checks or something else - it can be discovered, well, it is an uncharted territory.
