I have a 2001 Camaro SS with a LS3, cam and full bolt-ons. I am at the top of my injector duty cycle (100%+) with 2010 Camaro SS injectors (341s).

I am using the LS3 rails with the LS1 fuel system with a racetronix fuel pump and wiring kit. My fuel pressure is about 60-58 psi static.

Are there any LS3 style injectors that I can use that will be fairly easy to tune? Keep in mind that I have the LS1 411 PCM.

Something like these? They might be too big though.

Those are way too large, they are rated at 80LB at 43 psi.

I know I want about 50-60lb injectors at 58 psi. I just need to know which are easiest to tune with and have good street manners.

Tape the gauge to the windshield and go WOT to red line, that is the real test.

An LS3 injector will support ~650 Hp. What is your WOT AFR?

I am using the vcm scanner to log the injector duty. WOT AFR varies sometimes 12.8 other times high 13s. last time I taped the gauge it was 58 all the way up to RL. My VE is within +-4 LTFT and nearly 0 STFT.

Proper injectors and advice based on your engine and power goals, talk to Bruce at Fiveo Fuel Injectors (tell Carl referred you).
These are 50lbs at 43.5 psi, 60 lbs at 58 psi.

Their injectors are super accurate, and fast, I'm using their BlackOps series with 1600cc/152 lbs(!!) on my 6.0, starts and idles with no problems at all. It took my tuner 2 crank attempts to fire the motor up on these injectors. They are excessively big for NA but with E85 and turbo I will not run lean, and since they are so good at low duty cycle, why risk my motor with too small injectors. I strongly recommend not getting too small injectors, and don't get the cheapest stuff and risk blowing your engine.

Theres a sponsor here that rebuilds injectors to whatever you need.cant remember there name thou,when i talked to them they said i think? It was $200 and they will be matched set when there done.
