We have also tried a jaguar, and the drop off is less, but there is still a clear difference between forward and reverse. ???

If it is doing the same thing on a different SPARK, I am not suspecting that there might be something else wrong with your setup.
Here are a few things to try.
* Check that your battery is fully charged
* Change your PWM cable
* Change the port your PWM cable is plugged into on the roboRIO
* Ensure that your power wires are secured to the SPARK and your Power distribution board.
