OEM rev limiter is at 6750rpm so it has had at least the ECU modified.

a good number have been re-flashed by previous owners. Just got mine and turns out O2 wont show ready, even though stock cats and no DTCs whatsoever, so I have been calling around to EVOMS, Sharkwerks, etc to see if they have any record of a re-flash. Will probably have to have my local shop reflash back to stock to pass inspection. Ill bet OP just isnt aware of car's previous history?

Yes, Brazil... because had a problem in the tyre presure sensor.

The maximum boost pressure is stock.

1.4 bar is the highest it goes on the dash, it may be boosting a bit higher in reality, defo has more power than stock, 200-300kph is like 18 secs (roughly going off speedo) so 0-300kph in 29 secs which is a few seconds quicker than stock, I'd say its running about 580PS.

Impressive power and speed but have to say pretty dangerous and not for the faint of heart.

It is amazing how steady the footage is !

Here is one of my runs at the airstrip, if you compare the videos, the OPs does 156mph (250kph) to 210mph (338kph) in 37s, mine takes 17s in the video below, once over 250kph extra hp really counts !

I did not realize that after all these years that the dash display was limited.
On my 997TT, I used to see 14psi with 17psi of overboost. Now on my GT2 I see a max of 21PSI and on the GT2RS I see 24PSI.
And I always assumed that the boost pressure was electronically controlled with the VGTs and not with a fake dash display.
