Injector duty cycle was like 65%. Much lower when there is 93 in the tank or a mix.
I'm pushing 760rwhp through the 6L80 and Circle D 32-3400.

My ZL1 pump drops fuel pressure and maxes out quick on DC with E85.

That's before the DSX pump kicks on at 9psi boost, too.

Wonder how I could get it to kick on sooner like yours at 4psi?
