What Mods?

I have a '94' cobra with just a couple mods that runs a 14.3 1/4 mile. Can anyone suggest any cheep (under $400) mods to lower these times?.

My current mods include: K&N Filter, Hyperchip, BBK H-Pipe and Tower of Power Shifter.

The rest of the car is stock (gears, tires, fuel system, ect...).

Thanks.
