I currently have 12561462 which I believe are LS6 injectors.
My build
-Ported 241 heads
-Long tube headers/no cats
-LS6 Intake
-Texas Speed Torquer Cam
-Vararam intake
-Car was tuned by Speed Inc for this setup(or so I was told) but the heads were not ported
Will these be enough to support the engine, I pulled the plugs after a short drive and they are pure white(headers were hot and no codes).... I also have a set of Bosch 0280155759 30lb@43.5 injectors...
Your stocks should supply that setup.
when you tuned, what was the duty cycle for your injectors?
Based on my car, similar build. You run out of air way before fuel.
I had great luck with mail-in injector cleaning and matching with Injector Experts (https://cleaninginjector.com/).
They will be able to let you know if your injectors are flowing correctly.
