humm, installed fuel pressure gauge and this is weird... I just installeedd a fuel pressure gauge and when the key is set to on, I read 48 psi and with the car running 78 psi constantly. IF I get into boost the pressure will actually DROP to about 60 psi and stay there. It never goes above 78 psi, only down to ~60 under boost.
Im running a single walbro 340. Something makes me think I got a bad gauge or sending unit?
The stock regulator would hold the pressure at 60 always otherwise no matter what...
I was gonna use the FP data to determine if I need to install a second 340 inline before hitting the track tomorrow but right now Im stuck with this problem...

The regulator held 60psi with the stock pump due to the flow rate of the stock pump....more pump with the same restriction (stock regulator) = more pressure....78 does seem high even with a Walbro.
