I have a question in regards to the crit If you change your speed by 1 or more take a damage. If you use an engine tech to move 1 more spot after what your speed dial says does this cause a damage?

No.

Your Speed Has Not Changed .

Even if you're trotting along at 3, and run into something, and have to do a speed 1 maneuver to clear the obstacle, your speed has not changed , and you will only take the Ram damage, not an extra from the Card too.
