performance parts suggestions

i have a cold intake and cat back exhaust. im thinking about getting headers and a throttlebody, but not sure if the throttlebody will fit; the k&n rubs the hood already.
what other upgrades would anyone suggest for some hp?
besides the supercharger...:smokin:

You didn't specify year and engine, but a few other things that you could do are a chip/programmer, and/or cam.

They say that Doug Thorley's Tri-Y headers help the low end torque that trucks generally lag, mine are in the process of install now. The best gain I've felt was a low temp thermo, hyperteh makes it and claims you need the programmer with it, but i put one in without the programmer and had no problems at all. I got a decent gain from the superchips programmer, but be forewarned, I blew my tranny because I got greedy and kept bumping up the shift pressure untill it was maxed (thank God for extended warranties). But like said before, more details about your application needs to be clarified.
