    Hellcat Fuel Pump Duty Cycle question

    Hey guys,

    Quick question regarding fuel pump duty cycle. Current setup is a 2.85 pulley, 1300 injectors, lmi intake and cat deletes. Its currently 50 degrees by me, so I'm guessing it should read a bit higher, but where is the right spot for this setup? I'm seeing mid to high 80% at wot near red line.

    I can't tell without seeing a log but you might be getting all the fuel pressure requested with that duty cycle. Which is would be correct and expected
