On a stock LT1 engine. I know by March of next year I should have full exhaust, cam and valvetrain upgraded. I know that I am going to need slightly larger injectors soon. Is it okay to just go ahead and upgrade now to say 28 or 30# injectors? The reason I ask is because I am almost positive that I have a leaky injector now. I can't see how it would harm the engine, it would probably just have a lower duty cycle until the full exhaust and other upgrades.
Thanks and what brand do most people run?

 

I am not sure if you would want to run 30# inj.,but either way you go you are going to have to have the PCM reprgramed.

 

Dont upgrade till you need too. I ran the stockers with a hotcam kit and ported heads and my DC was like 92% with stockers at WOT. The stockers should be good up to 350rwhp or so.

 

Cool thanks guys. how can you tell what your DC is? LT1 edit, autotap? Thanks
