Did some pulls tonight (1433DA), nothing on the setup has changed. 3rd gear roll-in from 55mph, shift to 4th and back into full WOT.
Rail Pressure holds north of 2000psi for about 9s, then will nose to 1850 before the shift. Back up to 2800 and will taper slightly until redline in 4th with pressure above 2000. I wouldn't want it to get any lower in 3rd.
I feel that I am pretty much max capacity on E85 on LT4 fueling, but it would be hard for me to get the fuel rate up high enough in the lower gears to run out of pump, and it would be hard to do a pull long enough to nose the pressure over in a gear higher than 3rd. Redline in 4th is pretty much 145mph.

What is your low side pressure doing when your rail pressure is dropping? Your rail pressures make me nervous IMO... Also, what is your injector open time? I feel like these discussions should layout all 3 fuel system values (low side, high side, injector time) when evaluating fuel system performance.
