I have a 85' dodge ramcharger, and i have adjusted the carb, replaced the spark plugs, and catalytic converter. I am still in the dark as to how to get it to pass. Someone mention that racing fuel burns clean and if adding it to your fuel you can pass. Anyone know if this works? I have also tried the addatives from autozone etc, and it didnt work. Help.

The area in which i am failing is: HC(PPM) 169 rather than 127 at 15mph and at 25mph i got 118 while the max is 98. So the HC (ppm) is were i failed. I am also in Northern Cali

Not sure about a Ramcharger, but with my BMW it would need to be driven before hand.

And not for a few minutes at 35 mph. 15+ Minutes at 65+ MPH... And it would need to be tested in less than 20 minutes.

Sure your head is ok?

But your in a very strict area right? I live farther north where they have easier regulations.

well what would racing fuel do if i added it?

my father inlaw had his 81 cj set at 24 degrees BTDC and a new EGR valve for smog testing. This might help you I don't know, I live in VA.

I've heard different things about the octane deal.....not sure which one to believe. You definitely have to get your cat nice and hot though to have it operating at its peak efficiency. Also change your oil too. I've heard that if you have any wear in your rings that the HC's can end up in the oil and that you'll start burning those also when being tested.
