Needing help with Fuel Injector Size & PCM Programming I am needing some knowledgeable advice about fuel supply in my 89 IROC LT1!
I have done a lot to gain more air flow, but I am somewhat lost about fuel supply and programming problems. I have ported and polished my throttle body, the plenum and all its runners, the intake, and the heads. I am adding a badass cold air intake that I have added a fan to that turns 9000 RPMs. I do already have a stage 2 chip in it.So now how can I add more fuel to match the available air flow? I know that my factory injectors are like a 22# or 24#, and I could just go to a bigger injector size. Yet it's illogical to think that is all that has to be done! I cannot just go to a bigger injector without remapping that aspect of the computer correct? And if that is so, who can do that for me?

LoL, I'm not sure either....but it does look like a troll or bot.
Clicking on his user name does actually show a third gen with engine pictures too....so he might be for real.....but the engine is a L98(I think...)...not LT1.
So...I'll bite.
What is a full list of mods that has been done to this car?
