Default Colorado emissions

Any body out there been bit yet by the recent change in the exhaust gas standards implemented this pass January in Colorado, my 99 FRC has failed it's E-test twice (high HC) it is built with a comp Cam (228/236 duration, 588/601 Lift, 113 LSA), Kooks headers (W/cats), CAI ,stock heads, intake and throttle body. I have recently had the tune redone (actually made the HC worse) I am thinking the cam choice is my issue....
The standards changed from 1.22 HC GPM to 0.800 on Jan 1 2022, all of my previous tests (5) shows an average of 1.0 to 1.1 and would pass the previous standards
What say you..?

Thanks Ron W

Get a tune that makes no power and barely runs but can get you do the scammer, I mean sniffer, and try to pass. I've also heard you can pass emissions in your hot rod buy running the absolute ***** off it and get the cats hotter than the sun and immediately test. I don't think that will solve your high HC issue though. Vote with your feet lots of places don't have this nonsense like my area and we are doing just fine.

I'm sure it's not apples to apples. But my car is registered in one of the few Wisconsin counties that have emissions.
same deal, heads, cam, headers, unknown exhaust.
I took some advice from ages ago. I took it on a relatively hard drive for about an hour and a half.
Pulled into emissions and viola! Passed.
I think the tester and myself were a little surprised.
however, no sniffer. Just an OBD hookup.
