My acceleration is extremely inconsistent. I recently started really pushing my Q and driving it like it deserves, and sometimes the power is there when I floor it, and sometimes it's not. There's no rhyme or reason as to when the full power will be available, and manual mode doesn't help. I feel like it might be the transmission not wanting to downshift? Has anyone else experienced this? I have the shift timing update BTW.

Did your Q get the accelerator pedal update at the same time as the shift timing update?

Sorry, I didn't see this, forgot about this post and just made another one. Thank you. No, looking into it now. Is it expensive?
