You need to give it two encoders and a RobotDrive, and tune the gain slightly.

This seems like the way to go to me. It may not even be problems with the motors (or even if that does exist): friction in the drivetrain, imperfections in the play surface, wheel slipping (encoders attached directly to the drivetrain can't fix this though), among other things.
