It will also depend on which 3D engine you have: D, DE or DF. The ITT and N1 limits for the DF are significantly higher: OEI the 30 minute power is now 106.8% N1/885C, the 2.5 min limits are now 109.2%N1/940C ITT.

Don't forget there is a Cat A supplement which uses 103.5% Nr as well, for the EP. I'm not sure if this was approved for the HP: anyone know?
