Bill's SS

I am going to order AS&M headers and Y-pipe, 30lb svo's and have a custom tune done by PCM FOR LESS. I was thinking of adding a 52 MM TB to the list, is it worth it with the setup I have? How much more HP will I get from it? Thanks. Other mods in sig.

There was a good thread about throttle bodies in the advanced section. From what i got from that hueg thread wa that your better off oing bigger than you are going smaller. So if I were you I would get a bbk 58mm and leav it alone.
