In my opinion there would not be any advantage without removing the restrictions starting with the airbox through the MAF then to the TB. A 3.0 making 150hp will see almost 0 gains from a larger TB.
I assume crazyhayseed was looking for an improvement in performance otherwise he would have replaced his ill-running TB with another Pathfinder unit. In this case he saw issues with the factory software and tried bandaid attempts to make it work and threw in the towel.
Here is a pic of a intake mod that works well:
Other than that, save the hassle.
