You already have 23.2lb injectors from the factory, I think you could easily find something else for the money that will help in the power department. Heres a little tool to help you calculate what you need for injector size.

HP(crank)/ # of cyl/ .80 (max duty cycle 80%)* BSFC = Injector size

BSFC for a N/A motor is: .45 - .50 (BSFC is Brake Specific Fuel Consumption)
BSFC for a F/I motor is : .55 - .60

So lets say you have 265hp.

265 / 8 / .80 * .50 = 20.7

So even at a slightly higher hp rating than factory you still have more injector than you need. It would take about 300 crank hp to exceed the factory injectors.

On a stock engine with a stock PCM all you'll do is waste gas with bigger injectors.
