Chip in a 3100 V6 Engine? Other Mod's?

I have a 1996 Buick Skylark Custom with a 3100 V6 Engine. Recently I have been looking for any kind of mod's that I am capable of doing on my own, relitively enexpensively. So far for this engine all I have found is a Ram Air Kit, Upgraded Underdrive Pully, and a "Raceing Chip" called, "the Juice Box". I'm hoping some of you have tried these things and can tell me if they were worth it, or even worked at all... I'm sure that there are other things, short of a 3400 swap that can be done for better performance, so let me know if things come to mind. Thank you!
