Thanks dude! I’ve seen people with the same problem on Audizine/Mk6club and it was also commented by people there.
There is a rather long dsg delay when using launch control, but I'm assuming you are talking about a normal takeoff.
I don't know if this delay you are mentioning when taking off is just the DSG or the tiny motor lacking torque. I suggest you use me7logger to log the following when you accelerate from a stop in S mode with traction control off on a dry flat road. Stop when 3rd gear engages.
nmot - rpm
rl -load
wdkba -throttle plate angle
bfzgl_b -unfiltered vehicle acceleration
vfzg_w -unfiltered vehicle speed
gangi - dsg gear
and manifold pressure/boost (pvdks_w ?? check if this is the correct variable to log!)
Post it here and we can compare it to my car that seems to have very little delay.
