It means that you are able to do a lot, even gather strength that you didn't know you had as a result of grace. If you didn't have grace, then you wouldn't have the power to do what you do under pressure.
Grace under pressure refers to the behaviour of a person who is under a lot of pressure.
Say you're working as the boss of a team and you've got a deadline to meet, grace under pressure means you don't stomp around the office yelling at people, pulling your hair out, sweating and generally going crazy.
It means you retain a calm outward appearance and remain polite when dealing with people.
