Based on the fact that the motors from the Base to the GTS are essentially identical except for state of tune and smaller turbos for the Base, the 991.2 and 992,1 are unique in that tuning up a Base or S to GTS spec is no big deal. An APR stage 1 tune for the C2 will not unduly stress the motor.

Can anyone speak to the key differences of the powertrain of the base, S, and GTS? I know the block is the same but that doesn't mean much is cams, intake, exhaust, ports, oil pumps, or different metalurgy is used.
Does anyone have a difinitive guide on this or is it all Porsche top secret sauce?

Here you go. They are identical engine wise and John explains the differences between base and S/GTS turbos.

1. if i install S or GTS turbos on my base does the boost move from 12-16/18 by itself? something tells me it won't ... the ecu needs to tell the car to push more boost. so i need to add the turbos and then a tune, correct?
2. are the pure turbos significantly better for someone who wants a 100% reliable daily or is it best to stick with OEM?
3. i know the tuners discussed above all know what they are doing and i am probably being more cautious then i need to be, but i want to see a similar if not exact power band to S or GTS, depending on which turbos i went with. not more or not less. it should be the same unless someone out there wants to get more.
4. i will be tuning my base, which has a really strong motor and was broken in correctly but i need some of these things sorted out. i want a flat 0-60 car in 3 seconds or under at my altitude which is 4500 feet above sea level and a DA level of 6000-8000 ft. i am running 3.6-3.8 0-60s right now bone stock so i have a ways to go. 91 octane is all i have available so i need to be very careful if i could get 92 octane i would feel much easier about this but i am told i don't need 92 octane because of the attitude, which makes no sense to me but i don't know the technical side of this. does anyone know if this is true and is there a realistic solution to getting a 92 octane rating with some sort of addictive?

I am always amazed by the Joe Blows who "would never tune" risking their precious warranty and post a bunch of fear mongering BS here about things they really are not in a position to make judgements on. We all know that if Joes 911 is fast enough for him then it is fast enough for anyone.
Guys add 200 HP to these motors if not more, run the **** out of them and never have a problem but don't explode the heads of the anti tuning legion with any of that reality.

What's the general consensus on this forum and platform when it comes to tuning? Have you tuned your engine and/or transmission? If you did, why did you do it, and if you didn't, what's holding you back?
We've been tuning Porsches for over 20 years at APR. You can see a list of Porsche Models we tune here. It's not all of them, but a good chunk of models. The software we have is also on sale until the end of October right now.
When it comes to some of the other brands we tune, some of the more high end models, like the Audi RS6 and the Audi RS3 are heavily tuned. On the RS3 front it's hard to find one that isn't tuned. We see the same on some Porsche models, but on others it seems some are hesitant.
So, what's your take on tuning?

If it was so easy to boost the power, Porsche would do it.

I agree with your sentiment but you can’t add 200 horsepower to a stock 992 and run the **** out of it. It will heat soak after a single pull and you’ll be back to where you started. Now, with a bunch of supporting mods it is possible. But I don’t think it’s realistic for people to think a simple tune will accomplish what you are suggesting.

2) Both are reliable turbos. The GTS turbos have more mid range where the Pure's flow better up top, they make more of a difference at high RPMs.

Porsche can if they wanted to but they have a brilliant strategy to extract money from customers through their products and marketing. They kept the Caymans under powered for a long time for this reason. If their engineers wanted to, they could do anything the aftermarket companies do and then some but they have global regulatory stakeholders, shareholders, accountants, lawyers, marketers, etc. As most Porsche fans know, they make small tweaks to a proven formula over time. They need some runway for their long term strategy.
