Do you have the DSG ("Auto" transmission)?
I have no chipping experience, and this is my first turbo car, so consider that when reading this, but I have the DSG, and have come to the conclusion that the lag at launch is not really turbo lag so much as the clutch letting out.
DSG isn't really an automatic transmission - It is more like a robotic manual transmission, if that makes any sense. If you pull out with light throttle, and imagine yourself letting out the clutch with your left foot, the feeling matches that very well. Give it heavier throttle, and the "clutch release" feels quicker.
Again, just my impression after a week of ownership, and if you have 6-speed manual, nevermind.
On a side note, I'm a former Alexandrian; lived there for 8 years before moving to Long beach 2 years ago.
