Just passed my bi-annual smog test on Saturday. I actually passed most of the measurements by a wide margin...except one.
At 15 mph, the maximum allowable emissions of HC (hydrocarbons?) is 54 PPM. And I came in at 53 PPM.
So I was wondering what that actually means. And what can be done to lower that number? Is there one specific component that is responsible?
I have a bored-out TB, K&N FIPK, Borla header, Carsound cat, and Gibson cat-back.
