Changes for Lash Cap

[Osman]

I recently noticed my fuel pressure drop off at higher RPM. In order to keep it close to desired fuel pressure I was planing on installing a LS7 lash cap to help with pressure.

Do I need to change anything in tune regarding fuel pressure, or do I leave it stock ??? I was never sure what regulates high pressure pump.

I went through a similar situation but decided in the Z06 HPFP pump. End changing some parameters in the Fuel system tab.
