Your software probably doesnt have enough clutch pressure, from what I have logged and chatting with some of the best DSG tuners out there, not all DSG softwares are created the same...
Go out and log 4th or 5th gear WOT pull and record blocks 10, 11, 12, and 19. This will log reported tq reading, clutch 1 and 2 pressures, and 19 is dsg fluid temp. If your not seeing over 13 bar of pressure, its all software related. My car bangs gears at over 500whp with close to 14 bar of pressure on high mileage stock clutches.
