2007 Ford F150 Traction control?

I recently purchased an 07 F150 XL standard cab short bed with the 4.6L V-8 and 2 wheel drive automatic 3.55 standard rear end. I have a couple of questions. First, is there a factory installed traction control keeping this truck from slipping the rear tires on a full throttle take off? If I take off slowly, it feels like it would easily spin, but floored it didn't it's not a big deal, in fact I kind of like it, (it keeps me from doing something stupid) but I am curious. Also, has anyone else heard of the intake hissing on these motors? Dealer said it was normal and nothing could be done. Others on the net have had the same problem. Just had a few questions.
