DR911s

I'm 76, and tuned my 2017 C2S. I admit that I'm a non-recovering gearhead/motorhead; it's apparently in my genes. My car has plenty of braking capability for the uses I make of it. I'm not ever going to get close the the alleged 191 MPH capability stock and 194 MPH capability as tuned, and even on a track, my maximum speed [my choice, the car is capable of more] is seldom over 130, and that's only once every 2 miles. The Carrera S model brakes are upgraded compared to the base Carrera. I chose FVD Brombacher because their tune is milder than many [most] others who seek higher HP and allow higher torque which may overly stress the PDK gearbox.

Don't overlook the likelihood that the tires fitted OEM at the introductions of the 991.2 and 992 cars have been improved in traction, too. Porsche and tire manufacturers are in constant development of their products.

Yep, braking distance isn't actually much of a function of the pads or rotors. It comes down to grip and ability of the braking system to make use of the grip, so tires, aero, weight distribution and transfer, brake balance, and suspension are the main determinants of braking distance. Bigger brakes are needed mainly for heat dissipation.

The nice thing about the FVD tune is that you can load and unload it yourself. No need to go to a shop and pay each time. 👍🏻

I was comparing the Cobb and APR tunes. The Cobb tune appears to be much less linear than the APR tune. I wonder why that is.

As it looks we start to get more tuning options that allow flash load/unload the tune. See COBB's announcement too.

I have never tuned my 991.2 cabrio and I don't plan on tuning my 992 (which fingers crossed should arrive end of year)
i don't feel like I personally need more power at any time but I also don't track the car and drive like an old lady (never had a ticket of any kind)
I am 40 as of last week if that is a metric that matters.

I don't mind whatever people do or don't. If tuning makes you happy more power to you. If you don't feel like tuning that is ok too

I assume you are talking about the bump in the torque curve. The M tune does the same thing though in the marketing dyno graph it looks more linear. I think you have to be careful about assuming the marketing dyno and the actual dyno will be the same. The Cobb dyno actually looks realistic.

c1pher

They have almost identical numbers. So you're saying APR made theirs look prettier or something?

991.1 Guy

I don’t know. I would have to see actual dyno graphs from each one to know

Look at the column headers on each. You can make pretty much any chart look good or bad based on scale.

It’s called smoothing.

If you want a detailed technical analysis of the 992, I would start with Porsche’s 992 Technical Workshop series. All the info is out there. You just need to research to get it.

As well as the cure for cancer. I was asking because I was sure it was discussed before, especially interested if there are differences in metallurgy but thanks.

Well, Master Deep answered your question yet you challenged his response. So maybe you should just research it for yourself.
