114-115% Idc :/
I did some logging and runs and discovered a couple problems, I was starting to get a lot of KR, like 8-10* all over the RPM band. I finally got that sorted out and now have maybe one degree here or there... I can live with that for now.
My injectors need to be addressed ASAP... I know the 8.1L marine injectors are around 42#'s, and the regular truck injectors are 31's, does anyone know where I can get some marine injectors for less than the cost of my first born??

Welcome to the club man.
I'll bet 75% of the trucks on here are pushing their injectors that hard.
I asked about it a year ago, and a lot of guys just keep running them like that.
Is it the right thing to do? Nope!
When you find some 42#s for $100, let me know
I was gonna get some 31#, but I wanna spray a dry shot, so they will be useless then.

on motor I was was rich which caused them to jump up even farther, but even with a good a/f I'm up almost 110%
the only thing done to the motor is a CAI, cam, and headers/full exhaust...
I'm beginning to think I've got the 19#'ersin there from an early truck, we all know how GM likes to mis-match parts. I could turn up the pressure but I dont want to overwork the fuel pump.

By "good a/f" do you mean a good AFR target in the tune, or an actual AFR that is what you'd want.
If it's the latter, then your tune is inaccurate and can be adjusted so that your injector duty cycle isn't reporting so high. In your case (you're speed density, right?) the VE table has values that are too high.
