Is the Viper Pro controlling rate or do you have a 460 also? For starters check your flow meter for something stuck in it. Then make sure it spins freely. From there write down what your flow cal number is and reset your flow cal to 1 and cross between the pins with a paper clip and see if the gallons climbs 1 for each time you crossed it.
From there and maybe do this first, make sure you have speed registering on your controller.
