what engine and is the car tuned for it? what ECU? power fc? AEM settings changed for it? does it smell like gas? is it flooded?

Who made the injectors and are they made for your car?

What motor do you have?
Are the stock injectors high or low impedance?
Are the new injectors high or low impedance?
What is the lag time of your stock injectors?
What is the size or your stock injectors?
What is the lag time of your new injectors?

Fuel injectors are simply machines but you need proper variables to make them work, if you do not have a way to change these variables, you are also dead in the water.
