Confused on what to run with 8psi--fuel pump,regulator??
I am going to be running 8 psi on a 94 GSR and was wondering if i am going to have to upgrade the fuel pump and regulator. I bought DSM 390 injectors and I keep hearing many things about Fuel pumps and FMU's. DO I need an FMU or just an upgraded fuel pump?? help thanks.

your stock fuel pump should be fine; i would advice against raising fuel pressure as fuel management.
get a boost chip tuned with your 390's

I am going to use a VAFC and I want to try to avoid all that other fuel upgrade stuff as much as possible. If I do upgrade my fuel pump to I need to buy a fuel pressure regulator too??
