Have you contacted ATI?

What were the measured interference values prior to installation?

ATI instructions state that the interference must be 0.0007 to 0.0009" for correct interference and that you should also use a little anti-seize on the crank snout when you install. If the interference is not within this range, the hub must be honed to obtain the correct interference so your pre-installation values are critical to figuring out how to get it off.

If there are no visible signs of corrosion, then the interference fit may be too tight. You may have no choice but to use some heat. Do you have a heat gun?

Good new, congrats

You might want to download the ATI instructions and verify your dimensions before re-installing.
