Boost referenced fuel pressure, w/ stock FPR ? I am using the stock, rail mounted fuel pressure regulator #24072P ( from 2001 Silverado ) on Magnuson TVS1900 installation.
Will this stock fuel pressure regulator TRACK Boost at 1:1 ratio ?
Are there limitations, or non-linearity to be expected with this set-up ?
.
I can see the fuel pressure drop a small bit at idle, and climb under boost.
Analog gauge has minimal resolution.
( Static fuel pressure is 52psi , very Mild tune, 4.8 liter, 212/218 cam, 42 Lb/Hr marine injectors, 3.7" blower pulley)

I actually have a Aeromotive boost referenced FPR hooked to my stock rails and lines. In order to achieve this I had to gut the FPR in my fuel rails and in my fuel bucket when I installed the twin walbros. Was a quick fix to my fuel needs but I would suggest it above 600 hp. Some are very successful here with stock rails but I'm switching to -8 feed/-6 return next month.
