I've found that when FMQing, I usually need to increase the bobbin tension to keep the bobbin thread down (for this reason, I have a separate bobbin case that has the tension adjusted that is used only for FMQ). You may even need to decrease the top tension if the top thread is "pulling" the bobbin thread up.
