Over sizing injectors

[Chassis 33]

Is there any advantage to be gained in significantly over sizing injectors? For example you calculate that you need say a set of 250cc/min operating at 80% duty cycle to get the power you want. Is there any advantage, or indeed disadvantage, using 500cc/min injectors and running them at 40%? Pressure pulses in the fuel rain becoming a problem maybe???
