| My gauge reads inHg, and it sits right at -20, so right around -10psi. From what I've seen it increases properly at a 1:1 ratio with boost, but its hard for me to watch past a certain point since my boost gauge is on my A-Pillar, and Fuel Pressure gauge is in my din slot. I noticed today that the fuel pressure will sometimes jump around a little bit here and there at idle. sometimes it will dip just under 40, sometimes it will jump closer to 50. Something is definitely going on. I don't know if the fuel pump controller could cause the issue, since running an NA pump controller with a TT pump causes no such problems... but if it worked for someone else, I suppose I'll add it to my list. I've been looking at an Aeromotive adjustable FPR, that I think will be my next step. Would anyone advise against this, even if I am only going to set it back to the stock level?? I don't really think there is any other things to check other than the controller; but again, that just doesn't seem to make sense. Any advice is appreciated.
