I have high flow cats. But all they do is check with the OBD for any codes and that's it. You can go up to 90 days in advance.

Okay I finally got this bug worked out. It was what Billy suggested, since I did a higher stall converter that was my problem. I had Justin adjust the tune accordingly and since I have been great!
