Sounds like regeneration to me. The big filter on your exhaust is going through a regen so it can burn off all of the soot that has accumulated inside of it. Horsepower level drops and injector rattle becomes more noticeable.

Nothing is wrong with it most likely. You either gotta get use to it or delete it and get a tuner.

If your worried about it, take it in. Probably nothing wrong though.
