Passing Emissions

[Dave Zug]

I was re-reading the "too high NOx" post and wanted to start a thread 
on the subject of passing emissions.  The way my state works it, I 
had settled on the fact that I'll just have to be waivered (spend 
$150 to repair and it can fail and you can still drive). If I can 
pass thats great so I'll try. Here are the facts I've collected from 
readings:

If your NOx is high:
use more octane 
cooler air is better
test in winter or spring.
Disconnect Supercharger belts (if its the type that can be)

So lets add some stuff. specifically what to do to ecm to help. on 
the buick list site there are links to "emissions" chips and there 
are also the stock chips available (bins). might be interesting to 
disesct them huh?
