Drag radials would help tremendously albeit. So would more practice. Don't know how people are running low 12's with a K04?
Your mph looks low. What are you shifting at? 2 things that have helped me the most are:
A. rev the shit out of it. i have a 6mt, but in order to get decent mph you have to shift as close to 7k as you can. never looked into the gear spread on a dsg car, but since the claimed hp peak is like 7k on the tune i think you would see the mph go up shifting higher.
my car will trap in the 106-108 range on 100 oct map shifting at stock redline
2. drive the car for at least 100 miles on the 100 oct map to let the car adapt. this has helped me get the mph up from 112-113 to 114-115.5 range.
i used to just put in 5 gallons and drive to the track about 40 miles away. now i fill up a week or two out from when i head out and it has helped eek the mph up.
Drag radials will help the e.t. i have seen about a .5 sec drop in the e.t. with them, but practicing getting out of the hole will help just as much. if you can get the 60ft down to the 2.0-2.1 range you would be tickling the 12's on street tires.
next time out try getting staged, rev the motor to 2700 rpm and when the last yellow comes on start letting off the brake and feeding in the throttle. slip the brakes like you would the clutch. once you are rolling a bit try going WOT.
if the car bogs really bad try stepping up in 200-300rpm increments until you find a good happy place.
