yup i had the same issue, running the same pump i couldnt push passed 16psi on the pem set up witht he DW pump passed that it was dropping and jumping in fuel pressure. started at 12v and dropped to 10.5V
i hot wired it with a relay from the battery in the trunk and then got 14V on start and constant 12V with full pulls.
the pump wants Volts to stay constant kuz when boost comes in it starts flowing.
