problem w/93 si hatch bogging out

when you start off it drives fine but when it gets hot it starts to bog out and won't act right. we changed the fuel filter, pump,sparks,plugs,and cat. but still the same thing.

bogging is a sign of running overly rich (to much gas) do you have any mods that can alter the fuel system such as bigger thens tock injectors, or a AFC Fuel Controller?

Does your car overheat, or when the temp outside is hot it bogs?
