Odd Lag Issue

Hey Guys, Ive been having some strange issues going on with my 11 GTI DSG. When I quickly stop at a stop sign then hit the gas quick my car starts to accelerate but right before it shifts into 2nd it stops accelerating for a split second then starts again then shifts into second. There doesn't seem to be any rise in rpm so I don't think its a DSG slip, but maybe it is? Very strange i can't reproduce it on purpose for whatever reason.

So what do you guys think DSG Mech Unit? Throttle Lag?

Thanks in Advance Guys.
