have a holset hx40 with a restrictor and idle set at 900rpm. measuring the oil pressure i read 5-8 psi at idle when fully warmed. about 70-75 psi by 7500 rpm. what are people doing to increase the oil pressure at idle for the turbo. just run a heavier oil? running 10w40. or just remove the restrictor. but it will run higher pressure by redline. i keep reading its suppose to not fall below 10psi at idle
