Also be aware that there is a dead band of ~ 4 pwm counts around the neutral (pwmXX=127) position. Thus 123-131 tend not to move the motor.

Also, The speed of the motor going full forward may (probably will) differ from full speed reverse.
I just do this:

Code:
...
if ((pwm01 > 127) && (pwm01 < 251)) pwm01+=4;

else if ((pwm01 < 127) && (pwm01 > 3)) pwm01-=4;
...
