Actually it is the other way around Ben. LLY's get weird at around 10psi where as the LB7 gets weird at 14 psi. 
But this can be used at least on a LB7 to our advantage!
Can you say 27kpsi!
You are correct about the FICM being the problem not the FCA (Pressure regulator in the Dmax world). The Cummins uses a Bosch ECM which does not need a FICM like the Delphi unit used in 01-05 Dmaxs. 06 Dmaxs do not use a FICM either and could really care less about input pressure from a lift pump.

this is alot of good info but does the FCA in the Dmax resemble the cummins one, mainly the sleeve that gets modified in the relentless thread? are the different for more fuel flow or would it be best just to modify mine?
