You have the data in front of you. There aren't any tricks.
If you try to run ANY more than the 50psi they recommend the pump dies off quickly. The problem is if you're pushing the DI system at all the HPFP won't be happy with only 50psi feeding it.
I have no idea what they do in Hellcats but this setup does not support what they claim on an LT.

High powered Hellcats hit the stock pump with 21 volts in order to make 900+whp. They also run over 90psi to the injectors which brings the fuel ceiling down on the pump. I have a racetronix 525 in-line pump in place of the Bosch 044 that comes in the Cordes Aux low side in my C7Z. Airflow shows the car is making right around 1,100whp and that pump along side of the stock pump with a voltage booster my low side is solid running E55-E60. Holds right at 80psi across the board and doesn’t budge. The pump itself kicks ass. SMG either sent out a faulty pump or the setup it self doesn’t work.
