Injector noise

I've read all over the internet about the dreaded injector tick that the LS3 has. Mine is particularly loud... almost to where it sounds like an exhaust leak (though it's not). Has anyone found a remedy for this problem yet? I haven't seen anything on the web about ways to fix it so I guess my questions would be:

1.) Can the noise be fixed with aftermarket injectors?
2.) Can the noise be fixed with aftermarket fuel rails such as Aeromotive?
3.) Can the noise be fixed at ALL or is it always going to be there, even with aftermarket injectors/fuel rails?

Thanks

Djpelosi if you find the answer to this please let me know. I have a 2010 Camaro 2SS ls3 and it’s making a ticking noise at idle and at low rpms while driving. If you are in any low gear and get on it for a second then disengage the clutch, it sounds like a sewing machine. You also can hear it ticking when at a dead stop reving from 1500 rpm- 3200rpm but goes away after that. Please let me know if you fix this bud!

might be what you hear is the evap solenoid relief valve located up by the throttle body. mine ticks when its cold and at low rpm's lift your hood, and start it and while at idle touch it while the palm of your hand and seeif that the ticking you hear. same with me that was it . I went one further the old ladies 04 cts had that loud ticking on the right bank, thought it was a coil short or injector. was the same thing evap valve. they mimic the injector sound and quit when under acceleration and when warm. hope this helps let me knowwhat you find out. the oldman...

I had a ticking I thought was injectors, but upon further inspection, the spark plug closest to the firewall on the driver side had backed out. Ticking went away after I torqued it back down and checked the rest to be safe.

Only injector issues I've heard of are for the V6. V8's are inherantly noisy due to valvetrain design. Can you possibly post a video?
