Why still no dive acceleration difference?

Acceleration rate in dive is product of thrust, gravity and drag. Same equations are used no matter the plane attitude. Gravity is the same in the game no matter what the plane is doing. Thrust and drag are inside reasonable margins under level flights and climbs so there is no reason to believe that they are wrong during dive, especially during the initial phase.

Maybe TD can tweak the FM's in this area.

We could but we prefer to have FM as realistic as possible.
