Ok here'* the latest. I've fixed the EGR pipe and redid my CAI. I've got about 4 degrees of knock and now my latest question is. I installed my JEt chip tonite and nothing seems any different. I didn't undo the battery when I installed it. It'* off right now and I was wondering if it'* necessary to disconnect the battery for the new computer to learn itself? BTW the stock chip will be going back in if I still have knock reduction as I've got a couple of things left to do before it will be ready to stay in.
