KTI ECU update for XCeed 1.4 T-GDI (140 hp) – delayed gas acceptance & performance hole

Hello everybody, with my Kia XCeed 1.4 T-GDI (140 hp, BJ 2020) I notice that the gas consumption is delayed. Especially in the lower speed range, there is a short power drop even after coupling before the engine runs through properly. I have already tried a gas pedal reset, as recommended in another thread, but that didn’t work. I should not be alone with the problem after a short research. Is there a KTI ECU update or another one for this model? Solution of Kia, which solves the problem? Has anyone had similar experiences or got an update like this and can report it? Thanks in advance!
