Chamber pressure, mixture ratio, and throttle limits can be adjusted operationally within the hardware’s margins. Engines on reusable vehicles are regularly swapped, inspected, and replaced. Process changes, minor part upgrades, and material improvements get introduced into the production line.
Flight data drives continuous tweaks to control software (throttle profiles, mixture ratio schedules, startup sequences, health monitoring). Those are software updates
I want you to look at the evolution of the capacity of Falcon 9 over its various design iterations. There certainly was a lot of optimization leading to substantial growth in capacity.
