ul-1 turn fin adjustment

I recently purchased a ul-1 hydro. I have the 40X57 prop on it right now. Which direction do I move the turnfin to help with the sponson chine walk. I have read different things on different forums. Do I angle the bottom of the turn fin to the back of the boat or do I angle it to the front. I also ordered the HUG racing air dam for the front.

Thanks

You need to try both ways as each hull is different try starting with the tip of the turn fin at 8 o'clock
