Cat seems to be causing low gas mileage....search for the post from Cap'n about his cat gutting and increased gas mileage. That also could account for your above maximum HC level.....but in order to pass the inspection right away, I also would get it really hot like pesuazo suggests. A bottle of 104 octane booster with a full tank of premium would also help.
I bought a car at the auction one year where the top speed on the highway was 60mph. My brother rode with me, and said I had just bought a lemon
. I took it back to the shop, disconnected the exhaust from the engine, tied it up and went for a test drive.....with no one with me, I reached 120 mph
on that Plymouth 400 Big block ex-highway patrol car. The difference in power even taking off slow was incredible!
Hope you pass the test next time! Good luck
