Does that year come with a surf system? I do not think so.
Otherwise, try a suck-gate on the opposite surf side. Add weight - depending on your crew side. Try running 100%/80% for the surf side/non surf side. Try 10.5 to 11.5 for the speed.
Bow weight will make the wake longer. Also, running 11.5+ will also make it longer.
If you are having issues getting the boat on plane, you might have to look at a different prop.

Thanks for the info. It does have the surf system.
Thank you so much!
Hello, I’m just new to the forum. I have a 2014 SC450. This was my second summer with the boat so I have a pretty good idea of the surf wave. Did you end up with a nice wave? I found with the factory hard tanks full, front bow sack full, upgraded rear sacks to Enzo style 850lbs per side and had them 100/80 surf side non surf side. Anywhere from 10.6-11.8 made a nice wave. Had to use the trim tab to get the boat on plane depending on how many people I had in the boat. The factory surf tab settings were all wrong too. There is a chart out there that Supra gave to their dealers to adjust when demoing the boat back in 2014. I have it but not with me now. The barrel wave is no good no matter what you do. You’ll need to upgrade that prop to a 15x12 for sure even if you are at sea level. I have a 15x13 on my SC450 and it sometimes struggles with the weight. I’m at 3000 feet though.
High Atl and a loaded down boat - normal for a more aggressive prop.
On my 22' and living in TN, I went the middle-of-the-road vs aggressive prop.
Ran 3-4K of ballast and the boat was telling me to re-prop.
After little switch, the boat ran good rpms and had a good hole shot.
