Fuel Pressure Setting
Any idea on what the fuel pressure should be on a 99 si with a t3/t4 turbo running @ 9lbs of boost? right now it is running at 40psi (stock setting) but I am about to intall a Cartech 12:1 FMU, also does anyone know what that little set screw does on the side of the FMU right on vaccum line hook up? it doesn't say in the instructions, I know the top one adjusts the pressure?
