None whatsoever unless you're currently using a 4-inch tube
If the marker is chronying at less than 300, you can turn it up a bit, but there's nothing you can do to make it shoot further (except an Apex barrel but folk will point and laugh).
Or you can use a casting motion when you fire each ball. Like you do in fishing.
Might give you a few more feet.
I keep mine on factory settings (face it, Flash designed the board to work at its best. He then set that as factory) Why change the settings as he knows more than us. Chrono it up and you should be ok.
