I'd make a service call to your dealer. This isn't normal. I have a 2011 6.2 as well. I live in Texas and it never gets below 30 lol here in Htown, but I ran synthetic after 1000 miles just to be safe.

around 10hp or so from airaid jr. on mine.

CAFE and abuse.

Here's some recent photos I took after a year.
