No Lift Shift?

Anyone know if the 718 6MT offers an “unofficial” no-lift-shift feature? I know the 991 and 992 GT3 cars, and perhaps others, offer it essentially as an undocumented feature. My C7 Corvette also offered it unofficially.

By no-lift you mean keeping the throttle steady and just pushing in the clutch and shifting?
Wouldn't the engine over-rev? I wouldn't want that feature. I don't have that much money.

Yes and no. The point being with the feature the engine doesn’t over-rev. The RPMs are held, or at least don’t drop as quickly. It’s essentially the reverse of auto rev-matching for down shifts.
After some more digging it seems to be absent from 718s, including the GT cars.
This is from a GT3 manual:
“When the throttle blipping is switched on, a controlled throttle boost when upshifting and downshifting ensure optimum engine speed compensation"

Actually my 2021 BGTS4.0 has that in Sport mode. I've honestly not noticed it upshifting, but definitely downshifting.

Correct. Auto rev matching is absolutely a feature that matches revs on the downshift. Holding revs, or slowing their descent, for an up-shift is a different story.
