I'd double check by unplugging the map selector and putting the UTEC back on Map 1 to see if it runs good again.

Really, there isn't much to it. I'm guessing you did not put the UTEC on map 0. It is hard to rotate the switch when the UTEC is installed and screwed down, even with the kickplate and carpet pulled away. Try flipping the switch around and make absolutely sure it is exactly on map 0.

It's also possible something popped loose on your drive home from tuning. Maybe you have a vacuum or boost leak. I'd start checking hoses and such.
