+1 on K9's comments... That would mean you were flowing enough air to support 570ish crank hp... sounds like an X50...

I don’t have supporting documentation from when I bought the car. The car was sold to me as stock...which it obviously isn’t. I will post what I can see of the IC’s, but AFAIK, it’s a non X50 car, but I have no information on the turbos themselves.

you must then have at least a k24 car or you woudn't have a 1.2 tune - and even then that would not near approach 500whp without every possible bolt on helper known and then some.
if a k16 tuned car? try less. 375/400 whp tops! that with a 1.0 tune. if you have even our long disdained but loved by many
gt2/x50 intercoolers? for what you're describing now ( quick few on/off runs ) heatsoak won't be an issue for you. feel up the vents. if they are rough like cheese graters? they are at least the gt2/x50 i/c's.
i guess i'd ask. is your car k16 or k24.

Having enough fuel isn't the issue; you need the airflow to make that kind of power, so perhaps as Linwood mentioned, they are hybrids, if not X50, but either way, they are not K16s...

Markski usually runs 1.2 bar on hybrid turbos with 750cc injectors. In the past he used to recommend a 5bar fuel regulator, but not sure when he flipped to injectors vs the regulator. I have a Marksi tune along with his hybrid k16 turbos and 1 bar wastegate actuators. Take a picture of the turbo’s wastegate actuators, that will be a good tell if they are not stock. Markski is an amazing tuner and an is even better at customer service. If you know for sure it has his tune, he should be able to tell you what turbos are on it.
To your question about mods and track days, a better intercooler (997.2 GT2RS or Markski unit are good value) would bring down your IATs and keep it safe. I'm running stock (x50) with Markski tune, and this is what he told me. I'm not trying to go crazy power, so I'm in the search for some gt2rs units, which can be had for <$1k.

With no upgraded FPR or larger injectors, fuel is the issue at about 550 Crank Hp. I have a stage 2 X50 (forge ICs and DVs, 1 bar WGs, Kilne 2.5 exhaust, 1.1 BAR) that is tuned with the AP by Sambo using several data logged pulls and updated tunes. Sambo says I am maxed out at somewhere between 500 and 550 Crank without getting more fuel. My car has survived several track days and is currently a happy camper at 105K miles.

I guess I'm not sure as to the accuracy because I've only done one session (but it did consist of multiple runs).
I'll do some more looking and searching to see, but the car definitely doesn't have the X50 option (from factory).
Thanks for the tips!
My hunt continues!-Matt

If a dyno says my car has 555whp, that doesn't mean the next dyno I put it on is going to give the same results (in the case of my car, the dyno I was on is a type known to report out a bit on the high side).

Happens pretty much any time someone posts dyno numbers. The gist of the conversation is that no two dynos will ever give the same readout on the same car, so they are best used as means for comparison on your own vehicle (assuming you use the same dyno every time), rather than a way to compare two different cars.

but math was never my strong suit. still ballpark, i'd say.

is your rev limiter raised to 7200 or do you hit the limiter at 6800? that also would be a clue.
in other news today. i learned that my never ending saga of "pre-registration" smog tests are NO LONGER REQUIRED on either of my turbo assisted cars!
yay for me. was an annual nightmare in commiefornia.

I have an EVOMS Stage 2 Hammer tune (K16s with a Europipe), and according to EVOMS it produces something around 520 fwhp. I've never dynoed my car (and have no intention to) but I believe EVOMS arrived at their number through dyno evaluation.
Using a conversion value of 15%, 520 fwhp equals about 442 whp.
