I own one. I traded an 03 XTI for it. It rocked my world the first couple of pulls. I have had three different riders come out and ask me to tone it down a little. That power wedge really makes a noticeable difference. You can see the wake change shape as you go when you hit the button.
Everybody wants to see me sack it out. They just dont understand when I tell them, "I dont need it." But im going to try it anyways. Just for grins and giggles. Nothing like a 10,000 lb towboat.
