Never mind that it's a dishonest thing to do, but that won't help if the drive computer has already thrown a code that shows you've used tuning equipment.
You can delete the codes through the JB4 itself or a on OBD-II hookup, but you have to know what the codes are, and which ones NOT to delete. For the X1 the full code set has, to my knowledge, not been documented in public yet.
