I moved to Atlanta from Louisiana about a year ago. I had put most bolt-ons available on the engine. The headers are the BBK shorties...
. I did not hook the air injection up to the headers. The hook ups are still in my old state. Also, I added a Hypertech module that piggybacks between the harness and pcm. Put a 160 thermo instead of the 180, and I used a sensor that was faulty on my friend's water pump would keep the fans on all the time. I put that on and of course the SES light stays on , but the coolant stays @170 all the time.
. In Atlanta you must pass emissions every year. I knew it wouldn't pass so I have renewed the registration and insurance in Louisiana this whole time. I just got a letter last night from the insurance co saying they won't renew it anymore. So... now I will need to register here and pass emissions. Will this work: put a 195 'stat in, remove the Hypertech module, replace the waterpump coolant switch, and run 87 octane when I go to test. Will this pass w/out the air injection. The headers do have a catted Y pipe. Thanks for any help. Really, THANKS!!!

Might work. What year lt1 are we talking about here? A faulty engine temp sensor will completly throw off your a/f ratio, it may not even be entering closed loop mode, i'd take it off and leave it off. The 'hypertech' module should be taking care of fan temps for you or else you should install a fan switch.
I'd do the above mentioned but 87 probably won't help, combustion temp might become to hot and then you'll fail NOx
