Injectors?
What size injectors should I upgrade to on a fairly stock c5. I just have the vortex ram air intake, hypertech programer, zo6 exhaust, MAFT, larger MAF ends, power duct, and a 178 stat. Thanks!!!

SVO 30's. Once you upgrade your injectors, you'll need to have your PCM tuned to take advantage of it. LS1 edit is the best method.
lemme know if you need a tuner, I'm using a guy who's # 1

You probably don't want to do this. Larger injectors equal less performance unless you really need them. The fuel will be atomized much better with a smaller injector that is properly sized with the correct spray pattern.
Although they are called injectors, they really don’t inject. They just spray like a garden hose and they rely on the fuel pressure to get the fuel out. You can just think of bigger injectors as a bigger nozzle that puts out more fuel with each pulse. It seems that many people think they can somehow force more mixture into the motor with larger injectors and this is simply not the case.
You only want to go with larger injectors when your current ones are running close to max duty cycle and the car is going lean. This means that the PCM is already pushing the injectors as hard as it can, but there is still not enough fuel being supplied. This typically only happens with major upgrades.
