I set your FPDC to 100% so you wouldn't have any chance of the pump kicking off on you when you go from 100% down to 33%.

Yes I am running a relay that is triggered using the oem fpc --> fuel pump + wire and then sending power directly from the relay -> pump. The fpc still thinks that it is doing its job regulating the fuel pump duty but the pump is always running @ 100%. Figured that it would be the cleanest way to install as it prevents any cel's and is easy to revert back to oem. You can def hear the 450 running as soon as the key is turned before starting the engine.

I saw a large jump in amperage when I added a separate bulkhead fitting to run 10G wiring directly to the pump.
I retained the oem fitting and spliced my 10ga + wire into the oem + wire 2" from where the connector terminates.

Hardwiring the pump increased my fuel pressure from 50psi to 60psi. I reset the regulator to 50psi and logged some pulls and I am hitting the same IDC as running the pump through the FPC...
