move to illinois where your are exempt pre 96 or 97 i believe once i found that out, i had the emission/smog stuff off within hours :chug i believe here they just check to see that there are no trouble codes and u are good to go. doesnt look like thats the case there. im not sure how much you can mess around with the tuning to get it into the range u need it

Have you tried seafoam? It works really good.
