High Flow Injectors
Hey whats up........the question I have are high flow injectors really worth the money. And will it make any noticable power in a stock 305? I have a open air filter, k@n, Stage 3 ADS CHIP, 160 stat everything else is stock in the motor. And if they will make a difference where can I buy them and how big do I need to go?

U Drag,
The GM Powertrain engineers did a respectable job in mathcing the injector flow rates to the displacement of the engine, except at higher RPMs. The injector flows at anything but WOT are a function of the ECM, not the injectors. The ECM will control the injector pulse widths to maintain the correct A/F ratio at all throttle positions up to 80% or higher. This is the only place that a higher-flowing injector or higher fuel pressure will really help. You basically stock 305 probably wouldn't benfit much from different injectors, unless of course yours are malfunctioning.
