    Unhappy Zl1 Fuel pump maxing out at 45psi with Torqstorm supercharger

    I recently installed a torque storm supercharger on my 2013 Caprice PPV. I replaced the Stock fuel pump with the ZL1 fuel pump. At wide open throttle high am only having 45 psi max when I am commanding 65 psi in HP tuners. Any help would be appreciated!

    Dual-pump setup would be the way to go then, IMO.
