Hey everyone! We are super excited to finally start talking about a release date for the 991.2 Carrera and Turbo/Turbo S. Next week we plan to share some information about how the process will work, as it is different from anything we've traditionally done. For now, let's talk about power gains! Below are a few charts to give you an idea of what type of power gains to expect with the 991.2 Carrera, Carrera S, and Carrera GTS. For a bit more information, head over to the COBB Blog.

GTS master race.
Cobb.. Thank you for checking in and dropping this information. It feels like Christmas is coming.
AZ/Cali is stuck with crappy 91 octane. What do those number figures look like? Can we run a 95/91 octane mixture and utilize the 93 map? What about straight 95 octane, will it mess up a 93 map?
Will you be releasing more news such as stage 2/3 maps for cars with breather modifications?

Looks great! However, is it really necessary to always exceed the stock transmission torque limit which is 406 ft lb, even on the base car? Why o why?

The 991.2 Carrera transmission is a shared platform with the Turbo, per the technical details document posted here. ( the one about the 991.2 ).
Considering the torquey nature of the 3.0TT, this makes sense.

Don't do it. Stock car (even base model) is plenty fast enough. The S/GTS is already 40% boosted power, while the base car is 20% (and praised for being more 'NA-like'). Now with a tune you're making it 60%? That's a really boosty engine...
The GTS 500 HP figure is meaningless. I'd look at the torque curves. After tuning base < S < GTS by very small margins.
I don't think its wise to push the PDK to 500 FT/LBS torque when specifications state its rated up to ~410... maybe there is a reason Porsche designed the engine to not past ~400 torque...
I'm pretty sure Cobb isn't going to be replacing your transmission when it explodes. Porsche wont either.

Hear you on the power curves—much more interesting to me than the power itself. Color me curious, but also entirely happy with the stock "370" hp engine.

I have a stock GTS, doesnt seem boosty or non-NA to me ( except for sound).
Nick Murrays tuned vs untuned S video appeared to impress him with the power difference.
It is true that around town, below 4000 rpms, that all three cars will have similar power outputs.
On the track ( above 5000 rpm) the three tunes separate significantly.
I assume, people that get these tunes know the risks.

I can totally understand wanting more power, but when looking down at my speedo I remain thankful it's the "slow" 370 hp engine in my car.

The only way to truly tell is to drive stock vs Cobb back-to-back but from the charts it seems Cobb did a really really great job adding HP and torque without changing driving dynamic or shape of the curve. Definitely eager to hear user feedback.
