    Download the manual for free. Its all in the manual.

    I have a spare prefacelift and a spare facelift AFM if you are stuck (one has a 4-pin connector, the other has a 3-pin connector.)

    Where is Somercoats ?

    Battery voltage on supply.

    approx
    1V no flow.
    1.5V at idle.
    2V when blowing though it on bench test.

    But it usually indicates a big hole in the inlet system.

    I'm surprised it would start at all with 560s in

    To run 550s or similar, you need a Z32 AFM, a T28 or better and a custom map.

    If it had 560 injectors what chip has it got? Need a stock (or stage I/II H-dev) chip for stock injectors.
    Does it have an adjustable FPR? If it has it needs setting to stock pressure, 28psi at idle with vac hose connected, 36psi disconnected vac hose.

    Sounds like the OP needs to post the full spec, could be a right old muddle of parts.

    That could be a big enough leak to trigger the AFM failure limp home mode. If the AFM output doesn't match the rpm x throttle position within the tolerance then the limp home mode is set. Having a big leak of un-metered air means the rpm will he higher and AFM output low.
