Gen 5 Camaro Internal Engine Tech - Rough idle. Problem or not?

I have a new 2011 Cararo SS LS 6 speed and the idle seem a little rough to me. I have also noticed that when I barley get on the gas it seems to fade in and out a little unless I get on it. I have about 380 miles on it and wondered if this may be because it is not broke in yet or if it could be something more serious. I am an old school SBC guy so SFI is new to me. Any ideas?

No modifications yet?
I wouldn't take it too serious yet, it'll throw a light for sure on that car.
I know me personally I was over wary of issues just because It was new....
