I am not real happy with my Blue Ox Sway Pro either. I tow a 25 ' toy hauler. 1,100 tongue and 6,700 empty with a 16 F 250. The hitch was first purchased with 1,500 lb bars then I ordered 2,000 bars. Neither set of bars gets the sag out of the truck. The trucks built in sway system seems to fight against the hitch.
Do you constantly get the light on the dash telling you that it's activated? From what I understand the system doesn't kick in until you're in a obvious sway situation. A lot of guys seem to just turn it off when their hitch system has sway control already.
When it comes to the sag, have you been across a scale to verify that the hitch does or does not transfer weight properly between the axles? It could just be that the suspension needs a little help from an air bag or rubber springs.
