Dorch Stage 1 HPFP Review

///M248 · 04-01-2020, 04:25 PM

Hi Guys,

So I just installed the Stage 1 HPFP from Dorch, and here are my impressions so far.

Customer service was fantastic, I received the pump after submitting the VIN, but unfortunately since my build date is right on the cusp of production date changes I was sent the wrong wiring harness. A quick call and VM prompted a return call with 1 hour. A new harness was sent overnight the next day.

The pump install itself took us less than 3 hours. Great instructions and build quality seemed solid.

First run and I could immediately tell my fueling issues were addressed. After reviewing the logs it's clear as day the capacity is much greater.

OEM pump +PI - E85 @ 77%
PSI dips to 766 PSI

Dorch Stage 1 HPFP +PI - E85 @ 84%
PSI stable entire run
