Thanks Birdman. It helps a little. I haven't found a supercharger for the 2012 FJ, yet. It may be that there just isn't any available right now.
I did get the cold air intake and exhaust installed today. I had the dealer do it so that there can be no question of warranties and such.
I am very happy with the outcome. Not quite a drop you into the back seat when you hit the gas vehicle, but much better than it was.
