I have had the dsg stg2 on my ed30 since day 1 and recently flashed to stock dsg map as I was selling the car, it wasnt until then I realised how good the dsg map is. Car feels a lot more controllable, paddles are better to use as you know the car wont shift unless you tell it to, shift points are better in both s and d and shift points are higher allowing more use of higher rpm's
I should know this but I dont off hand, if the 30 day no quibble money back warranty is valid for DSG software, give it a try!
