i would recommend going from stock fuel filter/regulator to adjustable like Needswings adjustable regulator/filter.

thanks steven, i have stock mann filter with 4 bar inside regulator, i think about adjustable regulator and simple flow filter, but stock fuel pump and injectors can handle good afr to 20 21 psi?
