Well, I don't think torrified wheat has any diastatic power, but assuming you've got some pale malt or something in your mash it should still work out. The torrified might add a few more proteins than the regular wheat and make your beer a little cloudier, but if you don't mind that then I say go for it! Not sure what the potential is for torrified vs. white wheat, but if you're worried you could always grind the other wheat and throw it in as well. It'll still be tasty beer, and you might wind up liking it more!
