Has anyone ever had any issues passing the Philly CO2 emissions test with a CAI and 93 octane race tune? Just took it to get it tested and it failed the test - they said because the battery was disconnected it threw everything off and the computer needs to relearn everything before it gets retested, but I was wondering if maybe the CAI and tune could be the issue. help!

 

If your referring to the bama race tune fromAM then you would need to put the street or performance tune in and drive it for a while in order to pass inspection

 

Call your tuner and ask if your 02s are off. A lot of tuners turn them off in their tunes.
