    Air leak somewhere. Possible bad tune causing the high idle. I have seen this in other SW packages.

    The most likely thing is a vacuum leak.

    The general rule when you MOD is to do the MOD's one at a time. Because when something goes wrong or not as planned, it is harder to narrow in on the problem.

    You do not need to ever free air calibrate the aem wideband. Just go over all your work and check it carefully

    Throttle body gasket leak... Orrrrr...
    TPS is out of wack.. Flash over the tune again. Same tune. It does a TPS reset at 99%.
