Without a proper tune a better throttlebody really doesn't do a whole lot, on my 3.2 a higher flowing TB made higher rpm performance a bit better, but it was the tune to take advantage of the air flow that made all the difference in the world. If you actually want performance invest in HP Tuners and get them working on support for it. The above 2 mods really won't do much at all.
Also fun fact, all the bolt ons available on a V6 but without a tune, is still slower than a stock V6 with only a tune as a mod.
