Reading your original post, I'm wondering if your cigars were a little dry - e.g. they were taking up moisture when you switched to the Boveda packs.
You noted that the rH jumped when you removed the cigars.
Just a thought, but maybe your humidor is working just fine and your cigars need additional time - you'll need to keep fresh Boveda packs on hand until the humidor and cigars all stabilize at the desired rH. Boveda packs will eventually do that as they are a two way system.
EDIT: In case you were unaware, you can recharge Boveda packs - just put the dry ones in a small, sealed container with distilled water (in a small cup). The Boveda pack will absorb moisture until it reaches a saturation point at the desired rH.
