I've heard people say you can gain about 5 HP from just resetting the ECU. Is this true? How do you do this?

That's probably true, especially if the car has been driven gently for the last few hundred miles. This has been proved on dyno.

To reset, just unhook your battery negative wire (black) for 10 minutes or so and then hook it up again. Then go out and drive the car briskly for 20 miles or so.
