    Hmm, the boost code shows good voltage in the freeze-frame, so I'm going to speculate that it's not related to the "voltage too low" code.

    How exactly was it tested for boost leaks?

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Have you double checked the hose that runs from the N75 to the wastegate? Check that it's fully seated and tight at both ends.
    Have you double & triple checked that the wastegate was put back in correctly...they're harder to get wrong on your car but I've seen it.

    Intermittent mistakes are always the most annoying. By the looks of it, didn't occur simultaneously either.

    Have a look at the vacuum lines, like suggested by dafrazi. Maybe you'll need to do a basic setting/calibration of the new N75?
    Is the actuator arm of the turbo moving? In some engines there is an output test for this.
