Can you "legally" program out the emissions stuff on a '96?

probably not but i dont care im doing it anyway. all i want is for the pcm to read as if its functioning properly, if i tune the pcm will it show on the inspection screen that its been turned off?
i dont have any knowledge on pcm tuning at all so its new to me.
i know i can run simulators in the o2 sensors to make it look like its running clean, but i've never removed an air pump or put headers on an lt1.

if i pull all that stuff off with the engine still run without a tune???

your engine will run but you will have a constantly lit SES light, a GM dealer ship should be able to tune out the AIR pump if you ask the to you have to pay a half hour labor charge, I remember jegs was selling some sort of tuning soft ware that was good for the LT1 but I don't remember the name off hand, you best and cheapest bet would be to send it off for a tune, PCM performance is very good and the guy there has tuned alot of B-bodies and people on this fourms PCMs I don't know what it's like where you are but here in the Vampire state just about every shop will fail you for the visual inspections if you remove the AIR equipment, there are headers availible that let you retain the AIR system I would go that route and get a custum tune to deactivate it but leave it in and no one can give you hard time. That's probably the route I will be going in the spring cash permitting

thanks buddy! Here in MA (where i am) they dont even open the hood of the car or really look under it, but if they see a CHECK ENGINE light it will automatically fail, do you know if the light comes on because the pcm reads the pump is unplugged or because the 02 would read dirty?
I have seen the headers with the air bungs for stock replacement, I also havent seen them for under $500 bucks.
when i pull the motor and clean it down for paint i guess i'll keep all the stuff incase it doesnt run. headers are not a MUST for me but would definitely make things look nicer under the hood.
I have some good ideas for the engine bay, and some of them require as little as possible under there. im also torn on the a/c... it currently is a working system (compressor works and no leaks) but i really never use it, and it would eliminate sooo much stuff.

I believe if the pump is unplugged it will throw a code for it if the system hasnt been deleted from the PCM. Someone over on the big board actaully converted his car to work with an early PCM I don't know how or what that entails. I forgot who makes them I think Tri-Y makes a set of headers for the B-bodies that lets you retain the AIR plumbing I havent seen a cheap set of headers with the emissions goodies. I don't beleive an O2 code gets thrown with out the AIR pump mostly cuz these cars passed emmisions without them. Just the the "sticker" that on the impala SS superstore the say "this emissions system has been deleted for blah blah blah" So bang for the buck horsepower (as long as it isn't your daily you maybe out a car for about 2 weeks if you do this) Get your headers yank the AIR pump get the sticker and a tune to remove the system and optimize the performance so you get the best power with your headers. I agree that haeders really clean up a motor bay the stock manifold are hideous. But longtubes give you actaul horsepower so be ready to fab up some hookup pipes, atleast I believ that's whateveryone else had to do I still have stock manifolds.
