Shield Upgrade increases your Shield Value, which is the number shown on the pilot card. You start with a number of shield tokens equal to your shield value, and you cannot regen above your shield value.

A T-65 X-Wing has a shield value of 2, meaning you give it 2 shield tokens and it cannot regen above 2 shields. If you give it a Shield Upgrade, its shield value becomes 3, meaning it starts with 3 shields and cannot regen above 3 shields.
