The most you'll get out of a plug and pray ECU is about 15-20 HP. You can squeeze a little more out of a Greddy EManage Ultimate, but not a whole lot, until you start adding other stuff.
The Y-pipe is good for 15-20HP. Intake is good for 2-10.
IMHO, the most for your money, is suspension. You can go fast, but when you don't have to use the brakes to turn corners, that is when you leave the others in the dust.
