E-85 and Focus pumps

2003 Cobra Kenne Bell running at 17 PSI.

I have Focus pumps and 75 lb injectors. Question is do I need to upgrade my fuel system to go E-85. Im at 550 with a weak tune and pump gas.

Depends on the car an build many factors. So none of your questions can be answered

Yes you need to make sure that you pumps are getting enough volts data log an find out also adding bap with the wire upgrades will help. You should make 600hp easy with E85 if your pumps can keep up the volts an pressure.
