here is the testing manual from CA in PDF... so it lists everything that is pass or fail. The chip is generally hidden so most smog techs that are not well versed on diesel would miss it.... Might be worth using stock or have Bill make a no smoke tune if it fails under stock setting

Folks wonder why Banks stuff costs so much, other than all the money he spends on advertizing he pays lots of $$ to CA to get EO numbers for all his products... Not sure about Edge, Bill probably knows more if they have an EO number or not. EDIT: here is EDGE's take on EO numbers Edge Products: Customer Support

Maybe Bill can add more but I am sure as tunes are "Custom" each special tune would probably need an EO number... Oh, my FSR would not require emissions as its over the 14,000GVW... pre 1998 diesels don't require CA emissions testing either
From CA DMV website "Currently, smog inspections are required for all vehicles except diesel-powered vehicles manufactured prior to 1998 or with a Gross Vehicle Weight (GVWR) rating of more than 14,000 lbs , electric, natural gas powered vehicles over 14,000 lbs, hybrids, motorcycles, trailers, or gasoline-powered vehicles 1975 and older.
