Are there differences between 991 PDK & 997.2 PDK?

I think is more of a software update than mechanical.

Maybe, I am no mechanic... but I found the 997 more jerky, and also (relatively of course) slower. And the 991 has these little blips of gas when you downshift (Ferrari-style) which the 997 definitely doesn't. They serve no purpose other than the feel-good factor but when you buy that sort of car... it matters.

Sorry, never driven an Audi. I have not driven a F430 either but I have been alongside one on a track day, and it sounded exactly the same.
But I do remember how I grinned from ear to ear, every time I hit the left paddle, to get this little "wow" of gas that sounds brilliant. It does not exist with the 997 PDK, in any mode.
Cut a long story short, I brought the 997/2 PDK back slightly disappointed, yesterday. 20mn were enough to ascertain that PDK1 does not behave as enjoyably as PDK2.

I will get the 997TT. I couldn't wait 2 to 3 years without a P-car.

One small detail I did not know about.... in France, we now have a 6000 Euros eco-tax for that car. Even if you buy second hand... when you register it !!!
I am stunned.
I think I might move to plan B > take my car (997 Turbo 3.6L, 2007) to techart in Germany and get stage 1 or even stage 2... just over 600hp !!! for the price of the Eco-tax (stuff the Greens!!)

How do they do that? Re-flash the software? Can someone request a new software? From what I've seen, the answer is no, unless you have a real problem.
Also, I can imagine that Software changes would definitely improve shifting, based on more data gathered over the 997 PDK lifetime, so 991 could potentially have a better software... for some reason though, Porsche doesn't proactively update old Porsche software, kind of softly pushing buyers to new models for improvements... I totally hate their business practice... on my Audi, I had my ECU re-flashed a couple of times (once by dealer, once upon request) and it definitely improved engine performance and fuel consumption (adjusted how turbos engage, as well as A/F ratio).

That's exactly what I heard from my dealer when I asked if there's such a thing as a PDK software update. "Do you have any problems with it?" They clearly prefer to leave the PDK alone unless there's a real issue. Fine tuning it and tweaking it for our enjoyment doesn't count.
What I'm getting from this thread, as someone who's shopping 997.2s right now, is that the PDK has additional hidden maintenance costs/procedures (periodic "calibration") that you have to allow for when purchasing a car...in addition to those that are declared in the maintenance schedule. I think I'll be looking at manual-equipped cars only from now on. All I'll have to worry about is whether or not the previous owner abused the clutch, and I can get a round-about indication of that from the DME over-rev report and a test drive...and I'll be able to do all the maintenance (fluid changes) myself.

In 991, it gets much worse... the first 991S are arriving on the used car market here, in France, and the (extremely) few manual gearbox cars are clearly offered for less money, they are the difficult-to-get-rid-off models.
Add to this the fact that the 991 GT3 is sold ONLY in .pdk (albeit a much improved PDK!!) ... and you've got the trend... get a manual, quick, before it becomes extinct.

For a company that markets itself based on "excellence", I would think that Porsche would want to keep the software in PDKs that are already out in the field updated to the latest and greatest whenever possible...but apparently their business model (wringing every last possible dollar/pound/euro/etc. out of their customers) just doesn't allow them to do that.

Is the 991 PDK better - a little (maybe). But its not like a huge difference IMO. Granted I haven't owned one for years. But I'm v happy with my PDK. One data point for you.

I get your point, Rosky. It would just be interesting for you to drive a PDK2 (aka 991) for a few days, and I'd love to have your reactions... see if I got the wrong impression...
Just got my 997TT manual back after service... boy, don't think I'm ready to change...

I read you loud and clear ! Problem is that the manual gearbox is, apparently, dead as a dodo. I am (probably "was") looking for a 997TT 3.8L to replace my 997TT 3.6L, and I realise that there is not one car to be found without PDK. And this is only the 997 range.

And, by the way, your car is definitely a "keeper". It's really beautiful in white...I hope I can find the car that I want in white, as well.

Due to money constraints, I'm looking at 997.2 2S and GTS only, so no problem with finding a manual transmission...at least, not here in the U.S. It seems like roughly one third of the cars here are so equipped, and there doesn't seem to be any difference in price that I can tell, either. I am a firm manual guy myself...I figure if I'm buying a sports car purely for its on-road driving enjoyment (I don't track my cars anymore), why would I buy a car with an automatic transmission...particularly a car known far and wide specifically for its driver involvement (Porsche 911)? I derive great pleasure from shifting for myself; it keeps me more involved with the car. It doesn't matter to me that a PDK shifts faster than I do because I'm never in so much of a hurry that a few tenths of a second will mean anything. Obviously, this is just me, and I understand completely how someone else might prefer a PDK to a manual transmission. I can tell you this, though: if I had no money constraints on me, I'd still buy the nicest 991 available with a manual transmission. I think Porsche is uncharacteristically leaving money on the table by not offering one on the faster 991s. JMO...

So I'm keeping it. I had it fully tested (compressions, over-revving computer checks... -not sure how you say this in English- the lot) and it is good as new.
So, as I have had it 4 years, and I am itching for some change, I am going to go to Techart in Stuttgart Germany, and for a fraction of the cost of a change of car, get an extra 70bhp 550hp will be in 991 Turbo territory Totally childish, of course... but what the heck, life is short. I'll visit the Porsche Museum there , at the same time... always wanted to see it.
Re. PDK, I share your views entirely... or perhaps I should say "shared", until I had a 991S for three days, last spring. Now, THAT PDK impressed me, a lot. Which is why I started this conversation, by the way. Never say never, my friend... I was the fiercest opponent of the "automatic", exactly the same arguments as yours (and valid they are) but after three days, I took it back thinking "yes, I could get used to this one". It is blindingly fast, and the little exhaust "yaps" in between gears (both upshifting and down shifting) do make your hairs stand on end... trust me.
The 997S is a beauty of a car. I had two in succession. If you can find it in Carrara White (nothing to do with Carrera of course), then go for it. The only "fault" of that generation is a non existant sound. All it needs is a valves exhaust, CarGraphic for example (no shortage of Tuners in your part of the world) and you will have one dream of a car.
Keep in touch and let us know how you get on.
