I could very slightly trim up (maybe 10%) without issues but didn’t feel I was getting full benefit but it drove fine as well. If I went a little higher (20-30%) it would porpoise and not drove well. I went out with a friend one day and started playing around and went to 50-60% and it drove fantastic. It was much higher than I thought was logical but it literally floated on water and cut through everything with minimal slam on the hull even in choppy conditions. Don’t be afraid to play around - we were at about 3200 RPM/30ish MPH in this case which is a great cruising speed for the boat. Hope this helps a little.

Interesting, I would have never expected it to respond better at a point of trim past where it porpoised.
As several folks here have suggested, I still need to spend more time getting to know it and trying different combinations.
Based on your experience, I may need to think beyond my previous experience which told me to stop adjusting the trim level up when I started to experience porpoising.
Sounds like a good reason to get in more seat time next season
