How do you know when your injectors are maxed out?

My STFT's averaged 0.894922 from 908 to 688 MAF counts.
I multiplied those cells by 1.118509.
Pulled another log after the updating and STFT's average 0.874748 from 883 to 767 MAF counts. Below 767 the trims are pretty decent, 0.951422 from 766 to 728 and better there on down.

I was only logging STFT and MAF counts and only glanced at the WBO2, which read lean top end.

I'm running E-85, PZEV injectors (24#), Pro-M MAFS tuned for 24# injectors in a SVT sample tube. You guys know the rest of what's done to the car.

I'm going to update the MTF and pull another log. Just found it odd that top end didn't change a bit with the last update. I have 42#'er sitting on the bench but I'd really like to stay away from using them and keep the PZEV injectors ... may have to up the pressure to compensate?

*edit


Updated tune. Still lean at high flows. Trims from 903 to 809 counts average 0.871861. Even after adding 14%. Something's up.


FWIW, here is a crappy graph of my STFT's right now. 903 counts is on the left and lowest of 323 counts on the right, I was too lazy to make a proper graph.
