Saw another roadside SMOG test by CHP!!
This one was on Westminster and Seal Beach Blvd. They had a car on the dyno. This is getting to be harassment by the CHP.
Someone mentioned it's actually optional, so if you say you have to pick up the kids or something, they can't hold you. Not sure how true that is, but I'd try it.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
