just fitting bigger injectors will do nothing for perfomance, needs to be matched to the ecu airflow setting and the fuelpump

On the scoob youll be looking at being able to hit 350bhp.

But its a case if the clutch and gearbox can take it. But then again if your thinking doing it youd need uprated Fuel pump, A FMIC, bigger turbo to make it worth while, Lighten and balance fly wheel. Something else too, cant remeber if its an actuator or something like that. oh Tek 2/3 aswell.Something internal aswell cant think of there name

you only bigger injectors if your going to turn the boost up so much that the OE spec ones cannot flow enough fuel. I would suspect you'd need to uprate the fuel pump and pressure as well.
