so if it's randomly misfiring on all cylinders (since u tested that with the timing light), then you can start tracing it back from the coils. it's possible u have a faulty safc. since it's intercepting the signal from the maf, if it's telling the ecu there's too much air flow, the ecu will pull fuel. if the safc only does it for a split second, the ecu will have only pulled enough fuel for 1 or maybe 2 cylinders before resuming regular duty cycle. what you can try doing is installing stock 360's and removing the safc and see if that helps. just run wg pressure.
