Default Re: Headers , Exhaust and emisions in Colorado

Been a few weeks since I posted last, had a relative in town , a ski trip to steamboat and a business trip to LA last week but finally got a chance to spend some more time with the Z. She didn't pass emmisions on the first try, not even close. The car is running so lean now , its causing the HC to be over double the limit. It thought the headers and exhaust would lean it out some but not to this extent. I used an infrared thermometer on the inlet of the Cat and the highest temp I could get them to was about 380deg. New Plugs (ngk FR-5) are white after about 50 miles. I ran about 20 minutes while data logging with DataMaster but this is my first time using so I dont know how yet to post the log. I also have tuner pro but have not figured it out yet either. But it is definitly time for some tuning.

Tyler if you plan on comming to town, let me know as it would be great to meet up.
