I just picked my car up from the dealership today and, at first, they told me that it already had an "update" (the guy just would NOT call it a flash even though he was very helpful =P), and then they told me that all updates had been installed. They kinda change stories a bit but overall, they were MUCH more helpful than i was expecting. but thats a different story. Anyway, the reflash was indeed done because when I pulled out of the parking lot its like a FREAKING DIFFERENT CAR. GET THE FLASH - it pulls so much smoother and harder. You will notice it a LOT the first like 2 pulls you do and it will really surprise you; the car feels like a smooth torquey v6 instead of a rough 4. I've gotten a bit more used to it now but its really driving nice now. Definitely worth doing.
