What's been enhanced in the enhanced Medi-gel?

Solution 1:

The enhanced medi-gel heals more per use, how much your gel heals is determined by what difficulty you're playing on. So this would be more useful if you're on a higher difficulty than if you were on an easy one.

Solution 2:

The medi-gel enhancement basically DOUBLES your current medi-gel count, but the change is very subtle and easy-to-miss.

If you have 4 medi-gels after the enhancement, then using the medi-gel once will not reduce the number to 3 medi-gels on the power-wheel. You'll have to use it a second time for the number of medi-gels on your power-wheel to decrease to 3 medi-gels.

This is based on me playing the 360 version.
