I found this off the net which answers most of my questions but how much of an improvement can I gt from the following?




Air Filter Upgrade

Upgrade to a free-flow aftermarket air filter (K&N or Fram Air Hog)
Go High-Tech

Install a power module to enhance the vehicle computer.
Add an ECU

An Electronic Control Unit (ECU) can change fuel and timing to make your engine more efficient and powerful.
Cool the Engine

Add a new aftermarket cold air intake. The complete cold air intake will make more horsepower because it draws cooler air away from the engine.
Improve the Exhaust

Install an aftermarket exhaust, remembering that you will want a larger diameter than your stock exhaust system. Also the less bends the exhaust system has the better.
Go with High Flow

A high flow catalytic converter can also add horsepower.
Forced Induction Systems

Look into forced induction ? adding a turbo charger or super charger. You will need to make modifications to the fuel system, with the extra pressure in the engine you will need more fuel and at a faster rate then before.
