Any experiencing super low idle in 550i?

Hey guys,

Recently replaced my spark plugs, all the spark plug hinge-coupling things, and the fuel rails.

First thing I noticed is how low the thing idles when in drive at normal operating temp. Is ~525RPM normal? There's no rattle, shake, or anything. It just seems so low though. When I let off of the brakes, the thing barely has enough power to move forward on it's own, for whatever reason. Performance is otherwise unhindered.

Let me know your thoughts, here's a quick vid for reference (yes I know I couldn't have chosen a worse website to post my video to, I'm sorry for that).
