is this true and if it is how does it work?

I can understand the starter and headlights. After a few years of driving the electrical connections can get nasty. The new grounding could lower the resistance resulting in more power. However, you probably could get the same effect with a bit of sand paper on the contacts.

The smoother transmission and improved throttle response are all in his head, as well as the MPG improvement.

The other parts are legitimate.

Most cars run rather cheap wiring, resulting in a reasonably significant voltage drop across high-wattage circuits. The headlights being the biggest of these. Nominal voltage for headlights is 12.8 volts with expected life rated at 14.0 volts. Most cars, however, will push only about 12 volts to the headlights when new, which will represent a drop of about 20% in light output compared with the rated value. As the cars age, voltage to the headlights can drop as low as 11 volts, which represents a whopping 40% reduction in light output from rated value. If you can push 13.5 volts to the headlights, you'll get 20% more light than the rated value. This is why many people with old cars retrofit a relay setup to control the headlights to reduce the voltage drop. In almost all cases, retrofitting a relay control for the headlights along with solid grounds will yield far better results than switching to "extra bright" bulbs.

I upgraded a few wires in my car, the "big three." I replaced the alternator to battery, battery (negative) to chassis, and chassis to engine. I replaced all of it with 0/1 ga. wiring.

My lights no longer dim, and the car doesn't struggle as hard (electrically) with a good bass hit. I honestly don't think I get better mileage or anything like that, though.

brighter headlights is always a good plus :)
