I had unitronic on my VR6 FSI CC 4motion and it was a very tiny difference if at all. Not to mention losing MPG fuel ecomony. Like T-Reguan stated, you void the warranty. VW can tell if ECU was flashed or not as soon as it is hooked up to computer. In my opinion, whether it voids the warranty or not, i can think of much better things to spend 650$ on. Now if our cars were TSI or turbo charged, that's a different story. I flashed my 2.0T A4 before and it was night and day difference.
Good luck in your decision. Thats my person experience.
