ok. take some pics/video of the GSU while you're trying it. Let it run at 55 or 60 for a while to see if it shuts down automatically. If the GSU shows 100% in the top right (I could be wrong), I'm pretty sure the ECU should not be happy about that and trigger a shut-down with a low-rpm off condition.
