'Full rated takeoff thrust' is exactly that - the full rated thrust. Anything above that is technically an overboost. As I noted, you can get a little more than that due to the designed in headroom. You're not supposed to use the headroom except in an emergency.
If you're operating in Alternate mode, you can potentially get a
lot of overboost - especially on a cold day. Again, you're not supposed to go there.
