My specific concern is LPFP psi, fuel trims seem to be fine, nothing approaches 34. And everything else looks great, i'm not even in the ballpark of leaning out AFR wise, so my biggest concern with E85 mixes doesn't appear to be an issue here. Let me know what you think when you get some time to view it (obviously not urgent), thanks for the help. Anecdotally, the car is running mint.

50 is pretty low though even if your HPFP is still fine
meth can help btw, the DME will go negative on trims making the job of your LPFP easier. the only solution is an inline or upgraded pump
