I'm not quite sure which problem you're having. Is it:
A) Your robot is driving perfectly straight (or nearly so) but the encoders are giving you different counts at the end of your run, indicating that the encoders aren't counting accurately for some reason.
or
B) Your encoders are giving you different counts and your robot is veering off to one side (i.e. the encoder counts are right, and you just want to use the difference between them to be able to drive straight).
