BMW power pack - jb4. Opinions?

Hey guys just bought a 2010 335i and it came with the bmw power pack. Now I know it's a moderate stock tune but my question is if I go jb4 will I notice a big difference since I already have the power pack tune. Also is it a pain to take off when you go in to the dealer for service? Thanks.
