The Pantera IV is not a bow lift hull. They are totally different in the way they perform from any other BCB hull. They do tend to run flatter in the water at the mid range and even on top end, they are not as bow high running.
The P4 will not bust loose easily at the 3500 range by design. It will handle rough stuff just fine, and cut through it. Though what you are looking for won’t usually happen on your combination until about 4200 RPM’s no matter on propeller.
The Pantera IV is a very unique hull made for overall performance in rough stuff, and moderate top end. The mid range bow high driving does improve on the mid range if you lower the engine. It is a compromise for overall use in the design. Fishing to Top end!
We would set the engine to run it’s best at the top end, and adjust the hole shot accordingly at that height.
