Magnum cooling

Example, my Buick has a 3800 V6 with a factory supercharger. I modified the timing tables so it has close to 40° at cruise but once the boost comes in it drops down significantly, WOT it's only about 17°. Picked up a noticeable amount of power and MPG compared to stock and it still doesn't get much into knock retard (has knock sensors that retard timing when pinging is sensed). Being a smaller-bore engine than a 5.9L V8 it doesn't need as much advance to get a complete burn.
