Upgrade Injectors?
Hello,
I’m new here and was wondering if you guys can help with a question I have. I have an 05 LS2 out of a Vette in my Camaro and just did a cam swap. My question is since the car will need a tune should I upgrade to a bigger injector now? My first tune before the cam swap the car had 389 RWHP. So I’m hoping the engine will make a noticeable HP difference.
my upgrades are Fast 92 intake, stock TB, LT’s, CAI, Texas speed torquer4 cam, 231/234 629 613 111LSA. Would I benefit from a little bigger Injector? I also might put some spray to it like a 150 shot. Also should I port the TB?? The car has a T56 and a 410 gear also, don’t know if that makes any difference or not.
thanks I’m advance for any help!!!

You will NOT gain anything from installing bigger injectors ... unless the injector duty cycle is now approaching 100% at WOT with the injectors you now have in the engine.
Your dyno tuner will tell you what the max duty cycle you have during a dyno pull (it's best to keep it at 85% or less)

I have a combo not too far off. I did add injectors when adding the heads as my duty cycle was 85% when tuned as part of cam install. Relatively speaking, believe that 85% is going to be about where you'll be with stock injectors and the new cam addition. Don't know about the spray's impact, that'd be a good question for your tuner. Here's specifics of personal build, stage 2 is where I was running 85% duty cycle...
