I just called to get some more information and the service guy said he's gonna get it to my friend who owns the dealership, so he can get it to me. He called it the Computer Flash TSB, if that helps at all. I asked him for a copy of the TSB so hopefully I'll get it, and we can put it up on here for anyone who has questions.

Honestly everything with my car was perfect as well, up until the light came on. It felt very fast, shifted smooth (now that I have 10k miles on), and handled great. But still, I may have only been getting 95% out of the car, versus now I may be getting 100%. And that 5% might not even be noticable to most owners, unless you actually have the change done. If you buy a car with 215 hp, but its running at 205, your still going to think its running 215 even though its not. Theres really no way to tell.

The part I find the strangest is that shifting has changed. When I drove my car home from the dealer I was like "Whoa" every time I shifted to second or third. You could actually feel the clutch bite in, and feel the power in the car. So updating the program in the ECU can certainly have a huge impact on the total driving experience.

And this is totally evidenced by guys who do stuff like the Upsolute chip, which is only another ECU program also.
