Update and resolution.
Replaced the fuel pump and Im now able to tune afrs for the 11s all the way to redline at <90% DC @ 10.5psi. Problem was a weak fuel pump. I put in a DW200. Thanks for everyone's help!

I'm starting to see more and more weak/dead pumps these days. I'm guessing age is finally catching up to these cars
