Sr20 injector (370cc)

I have just got my fuel rail adapted (distributor version) to take the sr20 injectors. I understand that they are plug and play besides extending the fuel line what I am wondering is....

Will the car fire with standard ecu with these injectors, will it idle/run? I am in the process of getting a fuel map over teamview to run those but I need the injectors fitted. I may downgrade the injectors to the red sr20 250cc injectors if the 370cc cause too much of an issue.

Has anyone tried or know any more info?
