I had my car smogged before I put in my ATI P series supercharger and it passed. However, today, I had a pre-test done on my car, and it failed big time. It failed the HC, CO, and NO tests.
What can I do? I assume it is the rich tunning (11.5:1). Should I put the stock injectors back in and then put a stock tune in?
Thanks for the help!
