    If they don't do a visual or a sniffer, and just plug in, then you'll be fine. The accessport, I am 90% sure, gives you the ability to eliminate CELs that would cause you to fail.

    Well, the main thing is that you can run into issues with boost creep, which is potentially quite bad for your engine.

    As Will mentioned, the AP will disable the typical DTCs that are triggered by the aftermarket downpipe. The only issue you may have is if there is some kind of an ECU reset right before you go to get inspected; I don't believe the readiness monitors are forced online like you have the ability to do with OpenECU (I don't have access to ATR, so I'm not sure if that feature is supported).

    Since you choose not to follow their instructions, Cobb has no obligation to help you (one of the reasons you go with an AP is for product support). It may work fine, it may not; you won't know until you try it. At that point, if it doesn't take the map well, you have one of two options:
    1) Buy a downpipe that has you in compliance with the requirements
    2) Get a custom tune

    If your problem is boost creep (rather than a boost spike / overboost situation), a custom tune will not help you, since that's a mechanical problem, not a tuning problem.

    You can force readiness monitors online with ATR, Matty. The maps don't force the monitors online by default, however.

    Doesn't surprise me that Bill implemented that feature
