Rev matching with Sport Mode - GT3 v/s GT4

The GT4's blipping is more in line with the timing of how I actually do it myself when sport mode is off, which is probably why it feels so natural (and reassuring, since the revs are applied as you enter the gate for the gear).
Is that a bummer for you?

No, never unintentionally gets in the way and pretty cool to use sometimes (totally seamless upshifts at any throttle). If you just drive normally (release the throttle while upshifting), you wouldn't know it has No-Lift available...It lets you rev match manually yourself on the upshifts too. The only time it engages automatically is if you hit the clutch and keep the throttle position totally the same (whether fully to the floor or some intermediate setting). Any movement of the throttle during the shift will disable the No-Lift...

Once on track, you'll find that you get into a rhythm with your shift and braking points and the Auto Rev Match becomes very predictable and reliable. I don't really bother with the Auto Rev Match on the road (do it myself there and I wouldn't need it on the track either if the pedal positions were better for my heel-toe needs - thinking about a Rennline adjustable gas pedal).
From my experience this weekend on the track, you are spot on. At times I automatically went to rev match myself and no auto blip would occur if I had my foot on the accelerator. If my foot was off the accelerator the automatic rev match would occur. I had no problems at all with the auto rev match if I did not have my foot on the accelerator. I had no problems with the auto rev match even going do 2 gears very quickly from 4 to 2.

The difference I feel is that the GT3 sort of changes to your driving style so it is weird. So feels inconsistent. But - it also holds on to the revs longer which takes some getting used too.
I think the GT3 more programmed for the track and GT4 to the street.
But after about 9 month I forgot about the GT4 and really do love the Gt3. Just a fine tuned, high strung beast

GT4 OEM exhaust but mic was externally mounted just above it on the license plate. I haven't figured out how to run the wire from the cabin back to the outside just yet on the GT3.

GT4 exhaust is not as loud as the GT3 but it does have a great sound/tone.
Porsche was no fool- the knew it would have an inferior engine but they did their best to make it sound a lot quicker than it really was in reality.

I think you nailed it. "Much later" may be .001 of a sec... but it seems so different. I'll keep on it and see if there is a rhythm. Glad to see the interest and input here...can't believe that this one is still on topic.

I haven't quite broken in the engine, but the car has missed a handful of 4-3 downshift blips. And maybe it was for the reasons noted above. I'll pay more attention next time. But a few times on a canyon run, it is disconcerting when the expected blip doesn't occur and you get an aggressive thump. I assume all of this is software and maybe Porsche can adjust it if it needs some work. My GT4 was so intuitive.

Would this have anything to do with why SMFW wasn't compatible with the 991.2 GT3 engine? Seems like for both no-lift shift and the observed differences in rev-match behavior the end result is tighter control of mid-shift flywheel acceleration/deceleration in the GT3.
