Last year we were unsuccessful with using the gryo, the robot's momentum would carry it past the 90 turn and we were never able to get a consistent turn amount.

If you carefully tune the gyro, with no deadband, and use it as a
compass; you can feed the error in the heading back into the
motor power. It keeps the robot on track when it gets bumped,
and it automatically corrects for overshoot in turns.
