You get what you pay for ... what does it show as thrust level on the nameplate (attached to the engine). This (should) correspond to the data plug.
From memory the -7 can go up to 27klb with two bumps available. To minimise engine maintenance cost just take what you need (and nothing more)!
Why would RYR want 27klb? A low cost operation is at 24klb
