Fuelling depends on the need to maintain wise AFR, injectors depends on the duty cycle.
Stock injectors are normally fine for NA applications up to 250-260, sometimes more.
Mapping it yourself? You know what mods you've got and I don't. You'll have to see what the duty cycle is. 92% and up is getting into worrying territory.
