i have a 91, 3.1 L camaro and i was wanting to mod it up some and i didnt know which mods to get that would open it up the most, like performance computer bigger throttle body ext.

 

forget about a throttlebody, cause they dont' make them aftermarket unless you want to fabricate one. try a search for 2.8 or 3.1 performance parts. assuming that you live in a non smog controlled state, get a set of pacesetter headers, and get a good exhaust.
