I've installed the ZL1 stock pump (without the aux sump line, that's currently on hold) and I'm having a 0x7E8: P2635 - Fuel Pump 1 Flow Insufficient code once in a while when the ECU commands 500kPA and receives ~350-390kPA but there are no drops in high pressure at these moments. Does anyone know what changes exactly I need to do to my tune to support the new pump?
Thank you
