I got the SCT Xcalibrator 2 and my car is running very lean. The Xcalibrator 2 has a section where you can data log but I don't know which A/F ratio section to look at. The guys at Street Stuff said I my A/F is running at 16 and it needs to be around 13. Should I just create another custom tune and have the motor run more rich? Then I would really like to see if I'm at a safe A/F ratio so I can get to top Byron on the 14th. Any help would be great. :headbang:
