You can never take any action while stressed unless you have a card specifically allow you to. The rulebook specifically states that it is not allowed to take free actions while stressed. (Though this could have been an addition after 2014.)

This upgrade card is pretty much designed for large ships, because

1. They almost never have boost actions but almost always have Crew slots. (One notable exception is IG-88, but he's Scum anyway.)

2. Large ships only become more vulnerable to ion tokens, they can shrug off a single one a turn. As long as you can avoid getting another one, it has no downside.

A good combination might be taking this on a large ship along with Push the Limit. You can do something from your action bar and boost without any problems. Alternatively you could take Advanced Sensors, this, and an action modification. This really is a very versatile card, but I wouldn't recommend it on small ships, there are way better crew cards for those.
