However the Srt-4 fuel system is rated at 58psi versus our 40something-psi since it isn't exactly 3 bar. The increase in fuel system pressure increases the flow rate, so the 750's could really be like 650's in our cars.
What are you using to control them? You can't slap on fuel injectors to the factory ecu and expect lots of good results.

There may be a difference in length of the injector, width of the inlet end, and pintle head.
The most obvious would be the injector clips. They're most likely different.

4) Impedance
WitchHunter Performance - Fuel Injector Types
In order to work with the stock fuel rails and electrical connectors, you need top-feed Denso style fuel injectors. The impedance type depends on whether your car has a resistor pack, and the exact plug type may vary.
2ndGen Injector Types
In order to correctly run larger fuel injectors, you must have an aftermarket fuel controller that is tuned for them. Note that different aftermarket fuel controllers may require a different impedance fuel injector than what your car currently has installed, so I suggest that you buy the fuel controller prior to buying any fuel injectors. If you install larger fuel injectors without a tuned aftermarket fuel controller then your engine will bog, produce less power, and get horrible gas mileage.
The pre-tuned Rtek upgrade chip is a popular choice.

The next step up is a piggyback fuel controller like the Apexi AFC, which requires a moderate amount of tuning. AFChttp://www.banzai-racing.com/store/fuel_controllers.html
A standalone EMS offers the most potential, but it requres the most work to set up. The most popular brands are Haltech, Microtech, and Apexi. You can see other options in our EMS subforum. I recommend getting one that has local support from a good professional tuner.
