Clutch delay valve

Hey guys,
I think this has been touched on before but do we have a clutch delay valve?
Coming from my n54 I was always pretty good at shifting fast at WOT. But I've done that a few time in this car and I usually end up getting on throttle before the clutch fully grabs the next gear.
This causes the clutch to burn unless I deliberately take my time which doesn't feel smooth. This is exaggerated when using sport mode. Comfort mode makes it easier.

I don't know for fact, but rumor has it its built into the clutch master cylinder or something. Not able to be modified. I'd love to be wrong though.
