In fact, you REALLY don't want that because it's a bad idea on a stocker and here's why.
The bigger injectors flow more fuel (obviously) but the engine's need for fuel has not changed. In closed loop, provided the injector sizing is not totally off the wall, the ECM will compensate by closing up the pulse width so the same amount of fuel as before is delivered but the injectors are open for less time. The trouble comes at idle and low speed when the ECM may have trouble consistently contolling injectors at such short pulse widths.
At high load, when the engine goes into PE and open loop, the engine runs rich because of the incorrectly sized injectors.
For a stock engine, use stock injectors. If the engine is modified for increased air flow such that you need more fuel, then consider bigger injectors.
