That's definitely a tweak to your meter cal. You will need to lower the meter cal value. Multiply your current meter cal by .97. The math is really easy with the situation you have with nice round numbers. This means that you're going to tell the system that less pulses coming from the flow meter will equal the same number of gallons, so you'll actually be counting up gallons on the Viper Pro slightly faster than you were before, so the volume will match up.
