The factory pressure relief valve on your Cummins or Duramax is designed to open as rail pressure increases to avoid over pressurization to the injectors. This relief valve is a simple spring type valve that begins to open as pressure incrementally increases until it reaches full open. As rail pressure is increased due to programmers demanding increased rail pressure and wear of the valve over the years, this valve loses its ability to properly hold the originally desired pressure and will bleed off prematurely. This bleed off causes less than desired performance and hard starts. Replacement valves are both expensive and will still fail. The best way to ensure you're getting the performance you're after is to install a simple block off to eliminate the failure prone factory pressure relief valve.

can this be used with stock injectors? i'm running EFI live by anarchy, egr delete, 5"" exhaust, bd boost builder,sinister throttle valve delete, [email protected] intake and glacier ccv delete kit...i'm sure i missed something else.?

Yes it works perfect for stock injectors. If you are running into rail pressure drop issues and it is the fault of the PRV this is the key. I would recommend a way to monitor your railpressures. Something like a Edge CTS2.
