Your stock K24 turbos will not get you to 550FWHP, just like K16s will hardly get you beyond 500-510FWHP, yet it seems that some cars trapped at 600HP equivalent with K16s..What does this tell you.
In any case, the output and programming of your engine seem great, it does not really matter, but this is just for the sakes of discussion. Trap speed is a good indicator, does not mean it is infallible, there is always a catch somewhere.
If TB's car does a 60-130mph in 6.9s and is 140lbs lighter than yours and worse aerodynamics, he should have around 650FWHP based on your dyno numbers. How much HP do you have TB?

A Carr Gt traps on a dragstrip 133-135 with a low 600 crank hp and you claim you are at 550 with a ~ 127 trap. 60 horses ain't making up 6-8 mph on a strip..............ever.
As for your statement that PAG underrates..........LOL, total chassisdyno tuner myth and why would PAG charge 15 k for the X50 upgrade for a lousy 30 hp but give you 50 FOR FREE ? BTW, by german law the manufacturer has to stay within 2-3 % of the advertised hp figures , fact not fiction.
In the early 70's the 911S was Porsche's flagship with top acceleration #'s up to it's ~230 km/h topspeed. The usual suspects for competition were from Italy , Ferrari,Lambo, Maserati and De Tomaso with sometimes twice the rated hp of the 911. It might come as a surprise to you but the 911 dusted them all up to 220-230 km/h and the above cars only had higher topspeeds. That was the difference with Porsche REAL hp and Italian threelegged PONY hp and nobody ever accused Porsche of underrating ever back then. It was just acknowledged that PAG produces to a higher standard.
I think I have mentioned ti before, if you want a somehow realistic chassis dyno reading you have to use a MAHA, but be warned, it spits out humbling low (read real) hp/tq and stresses the car for almost 45 sec not the typical 5-10 sec Mustang/Dynojet run.

The other choice is an engine dyno.

I think what we need to realize is that the dyno's used in the USA give different results to those used in Europe,the same way that a USA gallon is different a English one.
A 600 hp car from the USA would be around 540-550 in Europe

That sounds more reasonable than 550fwhp.
I am curious if your next stage will add to the peak hp or will "only" give more area under the curve. Better spool up and better breathing should shred some tens of the 60-130, any guesses?
The 542PS RS-tuning GT2 is a very good reference point. If you get to those times without touching the turbos that would be fantastic.

do you have a long term strategy for your tuning stages?
Ask TB what kind of money you can sink into non-packaged tuning parts.
BTW, what is your use of the GT2, is it more fast street driving or also track usage or even open road racing?
For street use in the US I guess ZC turbos from Kevin are something to consider.
