Can a custom tune accommodate this, as in more torque and possibly firmer shifts/less slippage? I'd be interested to hear your thoughts on this.

Custo tunes can help alot with firmness and shifting but in certain circumstances such as larger wheels the first step I'd take is regearing to 4.10 or 4.56. The other step I'd take is doing this valve body modification. Like these:

Then I would proceed to a custom tune.
