Modding Porsche turbos
Discussion
Now the 991.2 lineup is all turbo it’s possible to decently tweak the carerra range
Looks like base car is the most tuneable but even the GTS with it’s bigger turbos can get 520-30 bhp putting it in the same some as full fat turbos performance wise while keeping RWD
Prob is not many people seem willing to play around with these cars as still quite new
Are they many on here who have tried it and what has been the experience? Things I’m wondering
Base cars tend to dyno higher than specs anyway is there any clean before after data?
To what extent is the remap done - how does a tuner get to 520-30 as the reasonable amount , could they get a lot more but are restraining themselves or all maxing out and using the ECU limits to avoid doing anything too stupid?
The chassis I think is more than capable of the additional power , how about the gearbox , how diff is the Turbo S PDK vs the GTS?
Any idea of the real world gains don’t see much comparing a remapped GTS to other?
I know potential warranty issues are there that’s ok but want to be sensible

I think the cars are too new for many people to have done what you're asking. Throwing away a Porsche warranty, which can now be extended up to 15 years, and making your car much harder to sell/trade in is a big decision and it won't be taken lightly.
It would be 'cheaper' to buy a Turbo or Turbo S rather than a GTS if you're after more power.

Rather than play the numbers game and manipulate emissions tests via forced induction engines which are actually less likely to return favourable emissions in real world driving, like these cars should be driven; I'd rather Porsche got back to the defining principles of what a Sports Car should be: Drop 150bhp along with 300-400kg, fit a zingy N/A engine and concentrate on feel, sound, feedback...
They could even map it to lean right off at light throttle setting to circumnavigate the CO2 police.
Shame there are so few manufacturers left that consider the more purist elements for this type of car.
Right I'm off in my lag-free world to comb my beard in peace!

That’s slightly off topic...I do agree they could certainly make a better lightweight car than the alpine - however the alpine itself does not look half bad and now there’s a viable car on sale with those principles They could even map it to lean right off at light throttle setting to circumnavigate the CO2 police.

But does not change my question about the GTS - I am very happy with the way it handles and like to tinker around

Shame but it is the way of today.
The GTS is a great car and the potential gains throughout the 911 line up are certainly there. Don't get me wrong, I once owned a 1.8l turbo pushing out 640bhp so fully get this argument, I just feel that with every manufacturer singing the same song now, it gets a bit boring. I just wish Porsche could be a little more leftfield and get back to its roots.

I suggest you actually visit a 9e or Litchfield and meet Ken or Iain who run those firms. Techart worth considering too as instead of flashing like 9e and Litchfield they use a piggy back ECU and take over the warranty.
With firms like the ones I’ve mentioned reliability is more important than headline numbers or crazy performance stats.
Lots of other firms out there but as your questions highlight lots of them do no proper R&D and do not consider the long term reliability of the car they are tuning.
Personally I think all a GTS needs is a free flowing exhaust like an akrapovic

I'm certainly going to consider getting the Litchfield remap, exhaust mods, suspension/steering mods when I get past the 2 year service. I think it'll become much more common to do this to optimise a car that'll be mainly for the road. The mindset would have to be one of keeping the car for a good period of time and being prepared to write a big cheque should the worst happen.
I have a 2018 991.2 Carrera T, tuned by 9e with a full Kline exhaust system (200 cell cats) and its making 490 WHP so 540-550 PS at the crank.
My car has its own tune, developed via Vbox and laptop with an iterative process of driving, analysing and tuning rather than an off the shelf map or piggyback. It was transformed when I got it back, felt it was towing a few caravans before compared to now.
The intercoolers are the limiting factor on 991.2 as the airflow is poor (raise the wing to improve) but 9e have some better ones with aerospace cores in the pipeline. Fitting these along with an upgraded Sachs clutch and GTS sized turbos or bigger should see 600PS+. There's more there without these but Ken was being kind to my manual box in its OEM state
