You're lucky and/or your dealer is quite stupid, as a header obviously messes with emissions when it deletes the cat. Come to think of it, that might not actually mess with the warranty as it doesn't affect the physical running of the engine... completely when you've got either the MIL or SCT installed. It's a pretty grey area, actually.
As for the MIL eliminator, plug the SCT back in. If the CEL goes away then I'd say you might have a faulty MIL eliminator.
