O2 sensors don't work after 0411 swap L31 Vortec

[Supercharged111]

The 0411injector data was set for 3.00 grams/sec for the 24 lb/hr injectors using tuner pro. Injectors are running at 60 psi constantly. And I never tried that. I assume it wouldn't care but I could give it a try.

I don't know what you know, so bear with me here. Are those 24# injectors 24# at 60#? I believe many are rated at 43.5#. Did you use Tunerpro to make it a 5.7 tune as well?

I used tuner pro to change the injector data and remove vats...

Runs bad when cold, but after reaching temperature runs good ? So after reaching temp do have feedback from the O2 sensors.? The number 1 sensor on each side is providing a/ f ratio mix signal so what's going on that's diff' when warmed up?

Barely starts when cold. Plugs are wet when checked. As the engine warms up it gets slightly better. When it's fully warmed up I still get no o2 movement. The point of this post is there's absolutely no movement at all. Hot warm cold etc nothing

Is it my imagination, or are you running injectors rated for 43#, at 60# of constant pressure? And could that be contributing to a compound problem (i.e. two or more issues that haven't been distinguished and/or separated and fixed)??

Was there ever a solution to this problem? Seems like these kinda things rarely have a posted solution...
