I am a fellow Mass Stanger and I had to pass the dreaded Dyno test this year as I have a 90. Even years have to pass on even years ,odd years on odd years.

But they seem to catch up with you if you have not passed last year or just bought the car etc..

Even with my bone stock car, I had to replace my original O2 sensors, new plugs PCV and TFI, and a fresh oil change to pass the sniffer as I failed the first try.

You will need a buddy to let you slide on the visual inspection, even on the years you dont have to pass the sniffer. Luckily, the cats and fuel restrictor are the only thing the visually inspect. Otherwise it's a Run what ya Brung test.

Some members have reported getting good NOX and HC readings even with no cats, but the motor needs to be in a high state of tune for that of course!

Other states will inspect the whole motor for any non conforming parts like intakes or missing smog pumps. Of course most of the speed goodies also have E/O certifications already so they are leagal to use, but there are exceptions!

Oh yeah, the saftey inspection is pretty thorough now. They always checked the tires but now they dont allow any rust holes at all, and they always check your front end now for tie rod and ball joint wear. They require that they start your car and drive it on the Dyno, so any starter or trans shifter problems will fail you. Heck even a broken seat could fail you. Your Defroster has to work, and windshield washer too. Also a saftey failure does not allow you 60 days to fix, and failure of the visual inspection may fall under saftey not emmissions!

At least they dont take off the wheels like they do for a New Hampshire inspection, That takes over an hour and almost nobody will do it while you wait up there.
