Oddly, I can't find anything in the owners manual about that. So, if it's NOT in Limp mode if it has the usual amount of power

Wait, I did find it. Chapter 3 Page 69: ENGINE POWER IS REDUCED This message displays and a chime sounds when the cooling system temperature gets too hot and the engine further enters the engine coolant protection mode. See Engine Overheating on page 5-32 for further information.

It leads you around in the manual to different sections. I highly recommend you read up on what is going on. If you don't have the manual, download it from the link: http://justgivemethedamnmanual.com/chevrolet/2008-chevrolet-silverado-owners-manual
