I'm on my second 991 and no lag with either one. Test drive one you're interested in.

Driven pdk trannys in most years since 2008 in the form of loaners. They get better every year. My .2 pdk shifts sound like the Audi diesel wec cars. It's wonderful after I learned to work with it instead of fight it. Converted diehard manual guy even after having total pdk failure.

I'm convinced that - in my car, anyway - the "hesitation" or "stumble" only occurs when in "normal mode" with the auto start/stop function activated. If I hit the gas, the revs increase but then drop upon releasing the gas (as it is supposed to in the auto start/stop mode in order to conserve fuel). The problem with that algorithm is that sometimes, if I hit the gas, let off the gas, and then quickly gas it again, there might be a slight hesitation in the PDK transmission because it is dropping revs only to suddenly increase revs. This has never happed to me in sport mode or in normal mode with auto start/stop disengaged because the revs do not drop when you let off the gas as it does when auto start/stop is engaged.

Long story short (I know, too late), I would without, um, hesitation, get another 991.1 PDK. Phenomenal gear box. Why would I not get a 991.2 PDK? Turbo-charged engine. And why not a 992 PDK? Ha, ha, ha - #nubbin.

hah! I have considered this. I am glad however it is a known issue. In my case, the first time I serviced it the after market KN air filter was filthy so that was part of it. Knowing that, I needed to run some Techron (3-4 times) to clean fuel system. This helped immensely but the funky hesitation appears and now I know why. Operator. That said I am hopeful to one day move it up to a 991.1 - thank you

This has been a fascinating discussion and very informative. All has been well since the operator error and the much needed cleaning of dirty things (filter, injectors, throttle body). One thing learned is that the PDK fluid, also changed, was absolutely pristine, so either an inherent issue within the 987.2 of my year or just a funky anomaly. Either way, if I have posted this to the wrong forum - apologies- it was a rookie mistake last year. Thanks to all

We were talking about this a bunch 5 years ago when the 991's were new.

It's inherent in some cars and others it doesn't do it at all.

Truth be told, it's easy to feel if you drive your .1 PDK like a grandma driving her Cadillac. You're gonna notice it. Hell, you're gonna notice a lot of things. I'm still uncertain why it bothers so many guys. It's a 911. Even with the ones that do it, it doesn't wreck the experience unless you drive off from the light with 3% pedal throttle every time.

Like the other guys have said, go drive some. You'll notice it quick if it does it. It's not a PDK thing. It's an engine throttle management thing. We beat it to death that poor old horse.

It will do it or it won't. That way you can buy one and know it won't do it later.

After driving DCT for years, PDK is far advanced. There is no lag, no hesitation well for my 991 that is. It is near perfect. And with a Cobb tune it’s that much crisper!!

Coming from a 996 w/ Tip to a 991 w/ PDK, it's a different world. Have zero hesitation on my throttle, no matter Normal/Sport/Sport+ even with A/C on and recirculate, ventilated seats going, etc.
It's funny, forums are good for some things but I swear there are things people 'want' to notice or 'feel' after reading them here and other places, and convince themselves it happens. Coming from a music background, I heard this all the time on those forums about 'perceived' tones, sounds, you name it, it happened. Only thing annoying in a PDK is being behind someone in a manual from a dead stop when I want to floor it...

Slight hesitation when the engine is cold. once everything is warmed up no issue.
