That's quite impressive as what I searched on the internet most states have a limit from around 65-120 PPM of HC on the results I found with people failing. That being said I've also thought that some emissions test facilities favor certain cars. When I had my 87 Supra I had a hard time passing with all my original parts. My buddy in his 91 Camaro V8 (was in the late 90's) with a hollowed cat had way better scores than I did.
