my ride is experiencing low fuel pressure into engine during high boost or high speed...
i had changed my fuel pump to 280lph with regulator as well...while starts the car for awhile...
I intend to use my stock head unit phone+ phone- and tel mute using ear piece wire, since ear piece using 1 ear plug I could wire that to phone +-. My only problem is for the tel mute what wire from the ear piece...
