Hi there Stephen, 11.3 sounds pretty fast. We have a 2013 LSV and here's what works for us:
1100 rear surf side full
500 center full;
750 IBS full
wake plate 1/4 down
speed 10.5

Try emptying your starboard, and just have everyone sitting on the one side of the boat. With less weight, I found I had to use the wake plate more to get a better wave...
This throws off a great wake when we have a few people in the boat. If it's just my wife and 2 kids out, I'll sometimes fill up a 400 pound sac on surf side, for a bit of extra push for me (being larger)... Check out wakemakers if you're looking to upgrade your setup... )
