Drill Motor Inconsistency

We have noticed that the drill motors on our practice robot do not run at the same speed at full throttle. One of the motors is running as much as 20% faster in one direction and 5% in the other. The obvious affect is that the robot travels on an arc instead of in a straight line.
Has anyone else dealt with this problem? We obviously cannot try to fix this with HW because then spare drill motors will have different characteristics. Did anyone have an efficient SW fix for this?
