Re: smog test? (Bone Stock)
save yourself the trouble and follow your user name (bone stock) 
- meaning i would go back to a stock ecu, and if your dc header is the jdm version, i'd put that back to the stock one as well.
i do however, recall reading somewhere on here that someone did pass with a jdm header, but it was the oem itr version. but i haven't seen that happen quite often.
